Note: Unlike most other games listed under SugarWiki/AwesomeMusic, the OST for ''Portal 2'' is [[http://www.thinkwithportals.com/music.php available for free]] directly from Valve![[note]]And unlike some other developers they released the whole soundtrack. That's 65% more soundtrack per soundtrack.[[/note]]

[[folder: Cinematic ]]

* The theme from the trailer of ''Portal 2'', "Reconstructing Science", just doesn't want to come out from the listener's ears. ''[[http://www.youtube.com/watch?v=tax4e4hBBZc "It's been a looong time..."]]''
** There's also the music from the extended co-op trailer: ''[[http://www.youtube.com/watch?v=SYLodmGYcrQ "Don't disappoint me..."]]''
*** [[http://www.youtube.com/watch?v=4iFDPEO6vYA Later released without dialogue here.]]
*** Now that [[http://www.thinkwithportals.com/music.php volume 2 of the OST]] is out, you can get the track (now called "You Will Be Perfect") for free, or even [[http://media.steampowered.com/apps/portal2/soundtrack/02/ringtones/music/m4a/Portal2-01-You_Will_Be_Perfect_RT.m4a as a ringtone!]]
* [[http://www.youtube.com/watch?v=MJghR7CuxG0 Robots FTW]]... [[DepartmentOfRedundancyDepartment FTW]].
** Which is a remix of nothing else other than... [[http://www.youtube.com/watch?v=022pdmjQ6AI BRODYQUEST]].
* "[[http://stereogum.com/688961/the-national-exile-vilify/mp3s Exile Vilify]]", by TheNational, certainly counts.
* [[spoiler:[[http://www.youtube.com/watch?v=hNsBbPOLjZg The Part Where He Kills You]]]] is basically ''Portal 2'''s "4,000 Degrees Kelvin". Plays in one of the tensest moments of the game.
* [[http://www.youtube.com/watch?v=0XpgchQnaUY "I AM NOT A MORON!"]] starts off as a cheery electronic theme that turns into pure orchestrated ''awesome''. [[color:white:And ''scariness''.]]
* [[http://www.youtube.com/watch?v=YVMWVm4EFtI "You Know Her?"]] is a fittingly ominous track for GLaDOS [[OhCrap waking up]], [[FromBadToWorse killing Wheatley]] and [[KillItWithFire throwing you into the incinerator.]]
* [[http://www.youtube.com/watch?v=wrTPfQb8Aco "An Accent Beyond"]], a fast paced tune that fits perfectly with the situation.
* [[http://www.youtube.com/watch?v=Nr0doRFDUoE Bombs for Throwing at You]], [[spoiler: Wheatley's final boss theme.]] It's like "You Can't Escape, You Know", [=GLaDOS=]'s final boss theme from the original, except it is faster, more frantic, and [[spoiler:has some of Wheatley's {{Leitmotif}} mixed in at some points.]]
* [[http://www.youtube.com/watch?v=I67TEDxrcuM Cave Johnson]], we're done here.
* [[http://www.youtube.com/watch?v=vXjIIv1KCfw "Don't Do It"]]. It's played twice, first during the confrontation with [=GLaDOS=], and again at the analogous spot in the FinalBoss battle. What's awesome is how it starts out calm, then grows in intensity at "Please press the Stalemate Resolution Button", and then goes freaking nuts after [[spoiler: the BoobyTrap goes off]].
* With the release of the first volume of the official soundtrack, we now have [[http://www.youtube.com/watch?v=DuC6fqK1swQ The Courtesy Call]] from the opening without the voice over. And it's as awesome as you imagined it would be.
* [[http://www.youtube.com/watch?v=g822Y3BnYkY The Friendly Faith Plate]] is an awesome tune you may have missed.
* [[http://www.youtube.com/watch?v=TMqZKe-LEH0 Vitrification Order]], [[http://www.youtube.com/watch?v=gj9eKbIEZTY You Are Not Part Of The Control Group]] and [[http://www.youtube.com/watch?v=G0nxHMAV5wI Forwarding The Cause Of Science]] all count on their own, but they all become even better when you listen to them all together and see how the first two build on each other to create the third, and then combine with [[SerialEscalation another]] track ([[http://www.youtube.com/watch?v=Ar72ybiZMCY Music Of The Spheres]]) to create [[http://www.youtube.com/watch?v=nrX0qxIynDo The Reunion]], arguably one of the [[SugarWiki/AwesomeMusic best pieces in the game]].
* [[spoiler:[[http://www.youtube.com/watch?v=UwRN59I5unw Caroline Deleted]]]]. Even without knowing the context of the song, you can just feel that something bad is going to happen about half-way through... [[spoiler: even though something good happens instead.]]
* [[http://www.youtube.com/watch?v=c624QWR3CXI Your Precious Moon]], the music that plays when [[spoiler:Chell fires the Moon-portal. And yes, it is appropriately awesome.]]
* [[http://www.youtube.com/watch?v=TipclsHkYhg Omg, What Has He Done?]] The first half of the song leaves you feeling terrified at how wrecked Aperture has become... and the second half pumps you up in preparation for one hell of a FinalBoss battle that places the weight of all of Aperture on your shoulders.

[[folder: Vocal, Semi-Vocal ]]

* The ending song, [[http://www.youtube.com/watch?v=dVVZaZ8yO6o "Want You Gone"]], (spoilers, of course) is really good too.
** Like [[VillainSong Still Alive]], [[http://www.youtube.com/watch?v=2Z3IxMb2_TM it sounds better in a minor key]].
* Before the end song, the player is greeted with a [[http://www.youtube.com/watch?v=AomFG7QAvvY choir of turrets]].
** Some humans did it in [[http://www.youtube.com/watch?v=gFCKhUgIziU a capella, and it's pretty damn good!]]
** There's something about the [[http://www.youtube.com/watch?v=ltWFNVVPHIY music box version]] of the turret opera that just drives you to tears.
** And during the game you can find some of these turrets singing [[http://www.youtube.com/watch?v=0CnigmxebuA this.]]
* "[[http://www.youtube.com/watch?v=LEPZ-drnUKE Wheatley's Song]]", by Miracle of Sound.
* [[http://www.youtube.com/watch?v=IcBVf5Nq-To PotatOS Lament]]. This song only plays on the title screen while you're in the old Aperture Science testing spheres, but it's one of the most haunting, etherial melodies in the entire game. Despite the digital effects and the nigh-incomprehensable lyrics, the sheer emotion in [=GLaDOS=]' singing is enough to make you want to shed a tear.
* "[[http://www.youtube.com/watch?v=JZIVmKOdrBk This Is Aperture]]", a Portal-themed take on "[[TheNightmareBeforeChristmas This Is Halloween]]". Some of the voices in there are so good you'd swear they were the original [=VAs=]. [[note]]This is made even more awesome by the fact that all of the voices were done by the ''[[TalkingToHimself same guy.]]''[[/note]]
** The ''other'' [[http://www.youtube.com/watch?v=Di2wDDwxqHg Wheatley Song]]. VillainSong at its finest.
** "[[http://www.youtube.com/watch?v=4U_RvUYINpo If I Were A Core]], a single turret's lament about what it would've done in Wheatley's place in a parody of "[[{{Beyonce}} If I Were Boy]]".
* [[http://www.youtube.com/watch?v=C4KLv8Iuv7E Why Wheatley Why?]] really captures the emotions of most players when [[spoiler: Wheatley betrays you.]]

[[folder: Ambient ]]

* "Triple Laser Phase", a haunting ambient track.
* [[http://www.youtube.com/watch?v=75RLvXmAUeY Love As A Construct]], a beautiful track to accompany a relationship that will never be [[spoiler:until the ending]]
* [[http://youtu.be/m2SF9e23ApQ There She Is,]] a gorgeous tune that plays as Chell and Wheatley enter GLaDOS's ruined chamber. It's haunting and even somewhat intimidating, and it fits the scene perfectly.
* [[http://www.youtube.com/watch?v=PPZArzUIfkc Space Phase,]] a tune so calm, yet so saddening.
* [[http://www.youtube.com/watch?v=_tQyP3BVcL4 Wheatley Science.]] It's sinister, mischievous, and almost DannyElfman-like, and hints at just how badly the Enrichment Center is doing under Wheatley's control.
* Several pieces of brilliant soundtrack are missed simply due to perfect integration during certain contexts; notable examples include [[http://www.youtube.com/watch?v=1_ch0Aj-sws synthesized Bach when "flying"]] and [[http://www.youtube.com/watch?v=MIcASFQPj0E rhythmically whirring lasers when near welders]].
* [[http://www.youtube.com/watch?v=wgVTmt6t3hg 9999999]] is the very first thing you hear upon playing ''Portal 2'' for the first time. The first 1:07 are quiet and mysterious... and then, at 1:08, the full orchestra kicks in, letting the player know that, this time, the stakes are held even higher than they were the previous game.
* Players only get to hear a small snippet of [[http://www.youtube.com/watch?v=xhv8eNs86nk (defun botsbuildbots () (botsbuildbots))]] on the main menu during GLaDOS's tests, but the full song truly shows how awesome it is. It recycles a single melody a few times, and each time it does so, it grows in strength until it peaks at 1:53. Combined with the visuals on the main menu of the turret assembly line, the song provides a perfect feeling of Aperture's machinery hard at work, and how it all combines together to form an impossibly large facility.

* Smooth Jazz will be deployed in 3...2...1...[[http://www.youtube.com/watch?v=J5jifIoiwek DING]]!
** Now in the [[http://www.youtube.com/watch?v=MPxVMpeVRGI full version]]! The song is called Offering, by Larry Stephens.
* Oh no, [[http://www.youtube.com/watch?v=V0vIioDGpjo He's Playing Classical Music]].
** [[http://www.youtube.com/watch?v=nrnmgMdvI6U Machiavellian Bach]], actually. Now that volume's out. Adds all the bits together, for better, um, book-reading. One of Machiavelli's best songs, that, I know, not a moron...
** Also, the [[http://www.youtube.com/watch?v=1_ch0Aj-sws electronic version]] of the song that plays when you're being flung, and the [[http://www.youtube.com/watch?v=8PRvYiZXBBc mixture]] of the two. If you're wondering, [[http://www.youtube.com/watch?v=WYhMpbDCq4s this]] is where it came from.
