System Testing Playlist: 35 Go-To Songs For Audio System Testing

System Testing Playlist: Our Go-To Songs For Audio System Testing

System testing is a crucial step for any AV installation. It is important to test the boundaries of any audio system in order to identify areas where your system might under-perform and correct them before completing an install. In order to do that, you’ll want to play a variety of songs through your system. But not just any songs will do. It is important to build a proper system testing playlist. If you aren’t sure which songs are right for a system testing playlist, you can refer to our guide “The Best Songs For System Testing“. But, if you don’t feel like creating your own playlist, no worries, we have made one for you!

These are our team’s tried and true tracks for system testing and system demos. 

Use our “System Testing Listening Guide” to zero in on specific instruments and frequencies while using our System Testing Playlist.

Use this guide:

  • To quickly identify problem frequencies
  • To understand frequency ranges and the tones that occupy them
  • As a demo asset for clients and partners
  • For ear training

Song Breakdown

System Testing Playlist: Our Go-To Songs For Audio System Testing

In order to understand why we’ve chosen these specific songs, we ran each track through a Frequency Analalizer and charted critical frequencies during playback. 

Each colored line represents a specific part of the song that contains important frequencies for system testing. These are the parts/moments that make each specific track shine with a well-tuned audio system. If these frequencies aren’t coming through clearly, that’s when you know to go back to tuning.

This will help you know whether to listen for the vocalist, drums, or other instruments and which frequencies to pay attention to.

SYSTEM TESTING TRACK #1

Circle of Life – From “The Lion King” Soundtrack

This track has a lot of big moments. From the big vocal lines that open the song to the big drums that drive the chorus. The great thing about movie soundtracks is they are purposefully composed to be dramatic. And drama is great for pushing your audio systems to the limits.

Tin Pan Alley (AKA Roughest Place In Town)

The beauty of this track is in the empty space. With only three instruments and voice (guitar, bass, drums, vocals), you can clearly see the separation of each element on the frequency spectrum below. Even without the visuals of the graphs, it’s very easy to listen and identify each individual element with your ears. That means, it will also be easy to identify any frequencies that sound off.

SYSTEM TESTING TRACK #3

These Days - foo fighters

This is a great rock track to see what your systems are made of. But the best use of this track is to test how your system handles dynamic range. This track starts very stripped down with just the guitar and continually adds instrumental layers. It goes from soft and subtle to a Rock N’ Roll punch in the face within 60 seconds.

Get Lucky - Daft Punk

This track is all about the mix. You should be able to pick any instrument you want, and quickly and easily identify it in the mix. Everything sits in it’s own unique space and each element compliments the rest. From the low and bouncy bass track to the rhythmic and bell-toned guitar, even claps, clicks, and digital tones galore. All of this driven by an up-beat dance drumbeat. You’ll have fun groovin’ along to this one while tweaking your system settings.

Halleluja - pentatonix

Vocal clarity, variety, and dynamic range are the three kings of this track. As a fully acapella song, there aren’t too many frequencies hiding here. Everything is right there for your listening (and tuning) pleasure. The amazing thing is how low the vocals actually get in this recording. Avi Kaplan, the bass of the group, gets low! This is a great chance to listen to the quality of the vocals (reverb, brightness, warmth, breath) and the harmonic frequencies of the silence.

SYSTEM TESTING TRACK #7

It's A Long Way To The Top (If you Wanna Rock 'N' Roll)

The driving kick drum and repeating guitar riff leads AC/DC through this classic rock n’ roll drenched anthem. Listen to the quality of the distorted guitar. You should hear and feel the crunch coming through the guitar amp and if you really listen you can hear when the strings are strummed open vs. plucked and muted. It’s subtle but should come through a well-tuned system.

SYSTEM TESTING TRACK #8

Don't Wanna Fight - Alabama Shakes

Springy guitars, hard-hitting drums, and a signature squealing vocal entrance that is uniquely Brittany Howard. This track is a little “out there” but it definitely showcases some very unique textures and characteristics. The opening unison guitar riff with a not-so-subtle hint of spring reverb provides plenty of mid-frequency and high-frequency qualities to work with. Then the drums start with a big, fuzzy kick sound and some crackling, brassy guitar mid-tones. Then enter, the female vocal. Brittany Howard is one of today’s most soulful and emotive vocalists. And in this track, she delivers plenty of interesting vocal candies that are sure to showcase the flexibility of your systems.

SYSTEM TESTING TRACK #9

Hotel California (Live) - Eagles

A chimey 12-string and lead 6-string acoustic guitar open this live rendition of the famous Hotel California. Filled with mids, upper-mids, and plenty of high frequencies, this is one of our favorite system testing tracks. Of course, let’s not forget one the smoothest male vocalists of our time, Mr. Don Henley. What makes this track even more impressive is that it was recorded live. The live aspect adds some unique qualities in the overall harmonic resonance. With the help of a well-tuned system, you can almost close your eyes and imagine you are there, watching one of the great bands of our time live!

Gravity - John Mayer

Say what you want about John Mayer, this track is one of the most clean and pure recordings out there. Each instrument occupies its own space in the song and they all work together to create an almost weightless quality to juxtapose the track title. Pay special attention to the drums in this one. The great Steve Jordan lightly clips the high-hat throughout while double-tapping the kick drum and giving a firm snare snap with every bar. And underneath it all, a melodic bass line rounding out the low frequencies.

I See Fire - Ed Sheeran

Although Ed Sheeran’s quick vibrato and seamless vocal runs shine in the intro of this song, listen for the little Easter egg Cello note that kicks in at 14 seconds. It’s a bit difficult to pinpoint in regular headphones, but a good system should bring that frequency out. From there, pay attention to the acoustic guitar and layered male vocals. Then at 1:47 there’s a cymbal roll into the chorus where piano chords support each downbeat and a shaker part fills out the high frequencies. Oh, and what folk song would be complete without some violin parts? The song really gets big at about 4:00 in. Enjoy!

Angel - Sarah McLachlan

For a female vocal test, nothing comes close to this song. The reverb drenched Sarah McLachlan sings mellifluously through each word of this song. Her dynamics and inflections, when played through a well-tuned system, will stop you in your tracks and make you hang on every note. And, if you listen closely, you’ll be able to pick out a soft Cello at certain points throughout the song. This is a must have tune for any system testing playlist. There is one quirky side-effect – you’ll likely feel guilted into adopting a dog.

Summertime – Louis Armstrong, Ella Fitzgerald

It’s always a good idea to run some horn sounds through your system for testing. This collaboration with Louis Armstrong and Ella Fitzgerald hits you with a piercing trumpet, a smooth female vocal, and the classic, gravely goodness of Louis’ voice. It’ll definitely put your system through the paces.

IN The air tonight - Phil Collins

An instantly 80’s backing track will pull sounds from your system like no other track can. Then, enter Phil Collins. His vocal track has a really short delay added to it giving it an almost ghostly quality. Listen closely during the first chorus (before the beat kicks in) and you can pick out individual vocal layers and their unique qualities. Then, of course once the drum fill hits at 3:41 it’s all impact from there. Listen to how the bass line follows the drumbeat. A true classic!

Bird On A Wire - Jennifer Warnes

Hide and SEek - Imogen Heap

The great thing about acapella songs are usually found in the silence between words. It’s the breath and the reverberation that bring life and magic into these tracks. This one has all of that and a little something different as well. She uses a vocoder effect to automatically produce vocal harmonies as she is singing which introduces a lot of drama and suspense to the melody. So, listen to the way the harmonies are working together or maybe how they slightly fight each other. And, with a well-tuned system, you should notice those little moments that are happening in the silence between words.

Hello - Adele

A call for closure of a love lost and all of that emotion and desperation should ring clearly through your system. Adele is a powerhouse among female vocalists, and you can be sure that once the chorus hits, your system should send chills down the spine. Listen to the warmth of the piano and how the vocal delay decays into the corners of the sound field.

What A Wonderful World - Louis Armstrong

From the guttural voice of Mr. Armstrong to the high frequency hitting string orchestra. This classic features a number of instruments from guitar to horns to flutes to strings and drums. But maybe one of the most interesting qualities to listen for in this song is the trailing vibrator of Louis’ voice. He hangs onto it longer than most singers and if you listen closely after each word, you can just hear his voice barely singing the remainder of the note – almost under his breath. If your system can identify that, maybe you’re onto something!

The Sound of Silence - Disturbed

Disturbed may seem out of place on this list. But, trust us, this song is the exception. Their cover of the Sound of Silence has a cinematic quality from the first soft and low-frequency vocal lines to the triumphant voice-breaking, drum-pounding climax. Listen for the piano lines, string harmonies, timpani blaring, and acoustic guitar’s soft chiming, even in the most prominent sections. From the low frequencies to the highest, Disturbed doesn’t leave any stone unturned as they whisper the sound of silence.

A Change Is Gonna Come - Same Cooke

When it comes to male vocalists, not many can come close to the great Sam Cooke. Listen closely to the upright bass line and how it plays along with the drums. Then you’ll hear what sounds like a flugel- or french horn cutting through the mix with warm tones followed by a brass line pronouncing the arrival of a change that’s gonna come. And, listen closely to the timpani in the back as they add emphasis to the drum and bass line. Of course, don’t forget to pay attention to Sam’s smooth and character-filled voice as he effortlessly flows through this classic.

Gaslighting Abbie - Steely Dan

As a group of professional studio musicians, Steely Dan deliver an unmatched level of precision, restraint, and finely blended tonal flavors. The production quality of this track allows you the liberty to pick and choose almost any element to zero in on for system testing. Want to focus on lows? The bass track is clear, poppy, and perfectly synced with the kick drum. Looking to the mids? You’ll find there is no shortage in this song with horns, reed instruments, guitar, vocals, and a crisp and punchy snare throughout. Or, maybe you need to hear clarity in the high end. The guitar tone flies pretty high in the frequency spectrum right alongside the constant sizzle of high-hat throughout. This track has it all – plus a great male vocal track.

The Girl in the other room - diana krall

From a subtle tremolo on the opening guitar line to the light and tasteful jazz kit – this track leaves plenty of breathing room to easily identify different frequency ranges. But the star of this track is the female vocal. The presence of the vocal track feels as if Diana Krall is the girl in the other room and you are right there beside her. Listen closely for the high end as her voice delay decays into what feels like a large empty tunnel. The drums also bring plenty of crispy high cymbal work to latch onto.

Vocals and a beat – it seems so simple. But the complexity of this track is great for system tuning. Very rarely does a track feature low frequency reverberation in such an exposed manner. But, since there aren’t any other elements getting in the way, pay close attention to how the reverb trails off on the low frequency kick. And the snaps – they’re crispy and drenched in reverb. It’s a high frequency gold mine.

Wake Me Up – Avicii

The dynamic build from the start of this track until the beat drops will surely showcase your systems’ flexibility. It starts bare, with an exposed acoustic guitar and male vocal for plenty of mid-range listening. Then, the four on the floor kick pushes you right up to a crescendoing mix of electronic drum sounds and synthesizers for upper-mid and high range listening. Once you get to the beat drop, pay close attention to the high-end. Every off-beat has a sizzling synth sound that should shine through your system.

SYSTEM TESTING TRACK #28

Smooth – Santana, Rob Thomas

You might think a Santana/Rob Thomas duo would lead you to listen to guitar and vocals. But, really, when tuning a system, this track offers way more value. The real flavor nuggets lye in the Latin percussion track. Shakers and washboard fill the high-end, while congas sit nicely in the middle. And, when the chorus kicks in, the wurly piano adds great upper-mid and high frequency tones. Then there’s the brass line and bass line throughout. This song has a little bit of everything.

SYSTEM TESTING TRACK #29

Becoming Insane – Infected Mushroom

Over seven minutes of electronic energy to send your system pulsing down a different path. The constantly driving kick sound will give you a good indication of your low end impact and the reoccurring acoustic theme gives a little insight into your low-mid range. Several times throughout the track you’ll also hear some mid to upper-mid frequency sweeps.

SYSTEM TESTING TRACK #30

Lebanese Blonde – Thievery Corporation

The backbone of this track is definitely the drum track. From high-hat sizzle to punchy bark of the snare drum, your mid-range and higher frequencies are covered. Another thing to note is the stereo imaging in this track. The mix is done in such a way that you can easily imagine the location of each instrument in the sound field. So rather than each sound stacked on top of each other blaring into both of your ears, every instrument is occupying a different location in space.

SYSTEM TESTING TRACK #31

LOS – Rammstein

Like the track before, this mix is set up for great stereo imagery. The acoustic guitar opens up from the right side of the sound field. Then the kick drum hits front and center. You can imagine all of these instruments being played in the same room together and where each of them might be positioned in relationship to you, the listener.

SYSTEM TESTING TRACK #32

Money – Pink Floyd

From the sound of the cash register going left to right in the beginning all the way through, this track is like a conversation of sounds back and forth. You’ve got guitar stating an idea over here then answered by keyboard over there. The entire conversation is taking place over-top a tightly made bed of bass and drum goodness.

Umasha – Mickey Hart

A gooey bass line fills out the bottom end of this track covering and entire octave in one, constantly repeating riff. This is a good one to turn up for an AC Mains test.

SYSTEM TESTING TRACK #34

Reasons Why – Nickel Creek

The acoustic in this song is raw. You can hear the progression of chords to the left accompanied by n rhythmic pattern strummed over a muted mandolin in the right. The sounds of the pick (or finger) hitting the strings is as clear as if it was happening right beside you.

Canon in D Major – Johann Pachelbel, Music Lab Collective

Here’s a classic! A quiet piano plays a familiar melody to start. As the song builds, the pianist adds more left hand notes and begins to hit each key harder and harder building up to the emotive climax around the 3:00 minute mark.

Die Walkure, WWV 86B

This robust orchestral tune hits with brass intensity right off the bat. With bursts of percussion and trilling woodwind falls halfway through, you’re sure to hear the dynamic peaks of your system belting out.
