1. Subject Name Here - 1:44 A pulsing track riddled with high pitched beeps. Plays when the player acquires the Dual Portal Device that can shoot both blue and orange portals, in Test Chamber 11.
2. Taste of Blood - 3:06 A nostalgic track with hints of melancholy that plays when the player first encounters the Portal gun, which only shoots blue portals.
3. Android Hell - 3:45 Plays in Test Chamber 13, and again in the large room of Test Chamber 18 containing turrets.
4. Self Esteem Fund - 3:30 Arguably the most melancholic song on the soundtrack, this soft, lamenting track plays in Test Chambers 10, 12, and 14.
5. Procedural Jiggle Bone - 4:34 A wobbly, sci-fi-sounding ambient synth track that plays both on Portal's main menu screen and during Test Chamber 19.
6. No Cake For You - 4:05 A slightly creepy, sad track that plays in Test Chamber 16's Ratman den. Throughout the track, radio-transmission-like beeps can be heard.
7. 4000 Degrees Kelvin - 1:01 A dramatic, chaotic track that plays GLaDOS attempts to incinerate the player by lowering them into the fire pit on the Unstationary Scaffold at the end of Test Chamber 19.
8. Stop What You Are Doing - 4:00 A creepy ambient track that plays during the protagonists' escape as they traverse through the dilapidated maintenance areas and offices of the Enrichment Center.
9. Party Escort - 4:21 A soft, synth-filled ambient track that plays during the protagonist's first encounter with the Rocket Turret.
- The high-pitched ringing heard throughout the song may represent the Rocket Turret's aiming laser. This, however, is unconfirmed by Kelly Bailey, the composer.
10. You're Not a Good Person - 1:24 An intense percussive track that plays during the turret ambush towards the end of the protagonist's escape.
- This track shows remarkable similarities to the Half-Life 2 song "The Innsbruck Experiment," which was also composed by Kelly Bailey.
12. Still Alive - 3:05 The acclaimed end credits theme of Portal, sung by Ellen McLain as GLaDOS.
