Guys, this doesn't do anything to Portal 2, this drops files in this location:
C:\Program Files (x86)\Steam\SteamApps\common\Portal 2\Soundtrack\Portal 2 Soundtrack [Songs to Test by]
It might be different for you, just look for a word of a track in portal 2
It's pretty much the same thing as has
EDIT: As of a recent update after this review was made, this does do one thing: It allows you to play the songs of Portal 2's Soundtrack in your Music Library

If you don't own this game (yet), the OST is available for free from the Official Portal 2 website. There's all the music you find in-game, which make a total of 64 tracks and that's a lot.

I will give it a 10 out of 10, it's okay.
The music is good and each songs have very original titles.
However, most of these tracks sounds the same but the music remain very enjoyable.

In short, great songs, the cake is a lie and it's available for free on Steam if you bought the game.

Science isn't about why, it's about why not!

Here's the lyrics of the song "Cara Mia Addio" with translation:

Cara bel, cara mia bella!
Mia bambina, oh ciel (Chell)!
Che ella stima!
Che ella stima!
O cara mia, addio!

La mia bambina cara...
perché non passi lontana?
Sì, lontana da Scienza!
Cara, cara mia bambina...
Ah, mia ben!
Ah, mia cara!
Ah, mia cara!
Ah, mia bambina!
Oh cara, cara a mi...
Beautiful dear, my darling beauty!
My child, oh heavens (Chell)!
That she respects!
That she respects!
Oh my dear, farewell!

My dear child...
Why don't you walk far away?
Yes, far away from Science!
My dear, dear baby...
Ah, my beloved!
Ah, my dear!
Ah, my dear!
Ah, my little girl!
So dear to me...

Notes (from Half-life wiki[/i]):
  • The lyrics were partially improvised. "The composer, Mike Morasky was the driving force behind the Turret Opera. He wrote all the music. He requested that I use my legit voice (operatic sound) on some of the takes. He chose the takes to use. He asked me to make up some words. So I did so in my bad Italian." – Reddit Ellen McLain interview
  • The Spanish phrase "Que lástima" ("What a shame/pity" or, alternatively "lastima" (without accent) due to the emphasis "That it/she/he hurts") sounds similar and is widely misreported on the Internet as the actual lyrics.
  • Note that "ciel" ("sky" or "heaven" in lyrical Italian) is a pun on Chell's name, as it sounds roughly the same.
  • "She" is referred to GLaDOS.

Specs for Portal 2 Soundtrack:

* Format: MP3
* Soundtrack length: 3h 22m 20s
* Total size: 463 MB (including album art)
* 44100 Hz sample rate
* 320 kpbs bitrate
* Stereo

Steam downloads game soundtracks to a separate folder in your game's Steamapps directory. You can right-click on a game in your Steam Library, select Properties>Local Files and click Browse Local Files to access that game's directory.

This is not only free if you own the game, it's free even if you don't. The music itself is excellent, ranging from mournful dirges to ambient tones to intense electronic tunes - but you'd know that too if you played the game.

Personally, I'm very glad Valve decided to release the music for the Half-Life and Portal games for free with any purchases of the games themselves - with this game's music in particular being free for all.

Now here's an interesting soundtrack if I ever heard one. Very different from the soundtracks of first Portal and the Half-Life games. I guess it's similar to the Portal 1 soundtrack in a way, seeing as it still captures the Aperture Science atmosphere in the music. Portal 2's soundtrack was composed by Mike Morasky rather than Kelly Bailey who had done most of Valve's soundtracks prior to Portal 2. The change of composer is most likely the number 1 reason why these soundtracks differentiate from each other.

The soundtrack itself, besides being featured in the game, had it release throughout the summer of 2011 with one disc at a time from May to September under the name of "Songs to Test By". Instrument-wise it's pretty much 90% electronic sounds from a synthesizer/organ but with some orchestral pieces every other track. The sounds are very reminiscent to that of "computer" sounds, chiptune if you will, sterile tunes with odd rhythms and harsh bass. Random and chaotic comes to mind, but still with sequence and feeling. As usual, most tracks are not really worth remembering, as they probably filled a particular scene in the game and does not consist of much else than this electronic ambience.

There are still some amazing compositions here though, a lot in fact. It's clear that Valve focused on the soundtrack, as it's in compare with the complete Half-Life 2 Soundtrack + Episodes, in quality. 64 tracks are also way more than usual in a soundtrack, some of the tracks maybe didn't make it into the game but they're still included. All three discs consists of "hits" and keep the originality through despite the lack of different sounds. It does get a bit monotonous after awhile with too much beep boop, I have to admit, but it stays true to the genre. Sticking to the favorites is a good idea to keep the variety at ease, there are plenty of awesome, cute and goofy tracks, especially on the third disc.

Composer: Mike Morasky, Jonathan Coulton.

Here are some favorites:
Disc 1.
1. "Science is Fun"
3. "9999999"
9. "The Future Starts With You"
11. "You Know Her?"
16. "Hard Sunshine"
19. "Turret Wife Serenade"

Disc 2.
1. "You Will Be Perfect"
2. "Halls of Science 4"
4. "An Accent Below"
16. "PotatOS Lament"

Disc 3.
1. "Reconstructing More Science"
2. "Wheatley Science"
4. "Machiavellian Bach"
9. "Bombs for Throwing at You"
10. "Your Precious Moon"
12. "Cara Mia Addio"
13. "I Want You Gone" - Jonathan Coulton
16. "Some Assembly Required"
24. "Robots FTW"

Also "Exile Vilify" (Youtube) by The National is officially a part of the Portal 2 Soundtrack, but is not included in Songs to Test By.

This is the greatest soundtrack and game of all time.
Buying this game on the summer sales will be the best use of your money.
Heck, Even buying this with no sale is worth it and you can create your own test chambers! It's for science.

Seems a little odd to have the soundtrack as downloadable content with no way to really get to it.

I Applaued to both Valve and Aperture Science Psychoacoustic Laboratories for all their hard work in making such a beautiful sounding Soundtrack I now and then listen to over and over again. The best thing about this soundtrack is its free to install that's if you already purchased the game.

if not, you can always give support by purchasing an actual buyable Soundtrack in itunes: or listen to every track for free on Spotify before considering on buying the itunes version: .

If you want the music to all of the other games Valve has made l Highlly recommend you to get The Orange Box (Original Soundtrack) available on itunes as well:
