This game has a hidden developer message.
Audiosurf is a rhythm game where you ride a spaceship across a road collecting colored blocks. Unlike other music games, the music here is actually music files on your PC, meaning every single song in existence is an Audiosurf song, even songs that came out after the game's release.
That's a lot of songs.
Present in the laddermusic folder of the game's directory.
A 44-second flute song, possibly made for testing the track generator.
A Portal remix called "The Device Has Been Modified", credited under "Victims of Science". The song itself in-game appropriately uses the [as-portal] tag. Present in the comments section of the file's properties is a developer message:
Thanks for Portal Valve, you are awesome. Wow I didn't know this would have such a warm reception. I went back and put the effort into it that I should have the first time.
The song was included in an August 12, 2011 update as part of a Valve promotional ARG. When the player booted up the game, the first song they chose would be replaced by this one instead. This was disabled in a later update, though the song stuck around in the files afterward.
Each of the four sound effect themes contain three sound effects that go unused in the final game. "matchformedOLD.wav" is a unique sound effect, likely from before different sound effects were added for different sized block matches. "overfill_safehitOLD.wav" is the Windows Ta-Da! sound effect; it's unknown where this would have gone. "tilefallOLD.wav" is a Windows "ping" sound effect that is used in the game, but in a duplicate file.
An outtake of a line from one of the tutorials can be found at "rush down.mp3".

FRED: THEN WHY CALL ME IF YOU'RE SO UNINTERESTED IN THINGS PAST?? GINGER: ... FRED: RIGHT, RIGHT. DON'T ANSWER THAT. DON'T EVEN THINK ABOUT IT. THAT'S YOUR STYLE I KNOW. ANYWAY, I JUST THOUGHT I'D CALL TO WISH YOU A HAPPY BIRTHDAY. GINGER: ... FRED: OH MY GOD, DON'T TELL ME YOU FORGOT YOUR OWN BIRTHDAY. I MEAN, I KNOW YOU'RE NOT THE SENTIMENTAL TYPE BUT JESUS. THAT'S DEPRESSING. GINGER: ... FRED: WELL, ANYWAY, MY PSYCHIC WAS SAYING THAT WE ONLY KNOW WHO WE ARE IF OTHER PEOPLE REFLECT OUR IDENTITIES BACK TO US. I KNOW YOU'VE BEEN THROUGH A LOT OF SHIT SINCE YOUR ACCIDENT, AND I JUST CALLED TO LET YOU KNOW THAT I REMEMBER WHO YOU ARE. I REMEMBER WHEN YOU USED TO BE DANGEROUS. WHEN YOU USED TO DANCE. WHEN YOU USED TO DRIVE LIKE A MANIAC. I REMEMBER ALL OF IT GINGER, EVEN IF YOU DON'T. GINGER: NOTE TO SELF--BECOME PHONE PSYCHIC AND EXPLOIT WEAK MINDED PEOPLE FROM THE PRIVACY OF MY HOME. FRED: THERE YOU GO! SEE, NOW YOU'RE REMINDING ME THAT YOU'RE ONE SARCASTIC BITCH SO THAT I'LL REFLECT THAT BACK TO YOU TOO! ***** incoming file Audiosurf-1.0 accept download?

NO SWEETHEART, IT'S JUST A LITTLE PROGRAM I WHIPPED UP TO REMIND YOU OF YOUR PASSIONS--THE MUSIC, THE DANCING, THE DRIVING...YOU KNOW, SINCE YOU CAN'T DO THAT STUFF ANYMORE... GINGER: (interrupting him) LIKE I COULD FORGET THAT. FRED: ALL RIGHT, ALL RIGHT. DON'T GET TESTY ON ME. WE WERE HAVING A NICE CONVESATION FOR A SECOND THERE. JUST GIVE IT A TRY AND SEE IF YOU LIKE IT--IF YOU DO, THERE'S MORE WHERE THAT CAME FROM. A LOT MORE.

Unused text mentioning missions:
Sorry, but this song is too short for Missions. Songs must be at least 0.08 minutes.
Sorry, but this song is too long for Missions. Songs must be less than 25.00 Minutes.
Unused text mentioning a "Battle" gameplay type:
Battle: Collected block clusters become live ammunition. Fire them with a click. Left click to fire at the primary target and right click to fire at the secondary target. Hitting secondary targets doesn't earn any points, but it's best to keep their population down. Don't let any of your block columns get too high or you'll take damage and lose points.
