- "Still Alive", well on its way to cult classic status among video game tracks.
- It's even better with typography.
- What else could make "Still Alive" more charming? Having it performed by a children's choir.
- You want charming? Try performing it on a music box.
- How about this minor key version. It's even more villainous than the original.
- And, of course, the jazzy upbeat version that plays from the radios over the levels.
- Not quite beautiful enough for you? Try slowing it down by 800%.
- How about a dancehall electropop version? With shotguns.
- And here is Delicious and Moist, an upbeat Ska rendition of "Still Alive".
- Peter Hollens, who previously produced a cover of "I Want You Gone" from Portal 2, produced an acapella verison of "Still Alive" with his wife Evynne. Evynne's plastic smile, plus the fact that she doesn't appear to blink once during the video, sell the performance. Devin "Supertramp" Graham put together this version showing three Aperture employees using a Portal projector to lob cakes at random people.
- "4,000 Degrees Kelvin", which plays at one of the most tense moments in the game. It fits the scene perfectly, especially with GlaDOS' comments.
- The genuinely creepy music, "No Cake For You", that starts up when you discover the Room Full of Crazy. Now that's thinking with portals.
- GLaDOS' boss theme, "You Can't Escape You Know".
- While playing through Portal, most people don't consciously realize there's music. It's so subtly woven into the ambient noise, it's barely even noticeable, except at a few very key moments (the radios and "Still Alive", of course, but also the end of Chamber 19, getting the fully-functional portal gun, and so on).
- Self Esteem Fund kicks in right about the time where the player begins to feel the isolation of Aperture Laboratories, having seen no one but Chell and heard no one but GLaDOS despite all the testing they have been doing. And this song perfectly augments that feeling... it is quiet and atmospheric, but solemn, reflective, and tugs at your heartstrings, making you feel truly alone in these bright walls of the testing facility.
- Not strictly from Portal, but Put me down. Put me down. Put-put-put-put me down.
- Also not strictly from Portal, but both tracks by Silence, from the main menu of the mod Portal: Prelude.
- Ellen McLain once wrote her own song for GLaDOS, "GLaDOS' Song" (also known among fans as "Don't Say Goodbye"). One fan made a GLaDOS-ified version with music video.
