Most of the soundtrack is non-lyrical ambient music composed by Kelly Bailey and Mike Morasky, somewhat dark and mysterious to match the mood of the environments. The closing credits song, "Still Alive", was written by Jonathan Coulton and sung by Ellen McLain (a classically-trained operatic soprano) as the GLaDOS character. A brief instrumental version of "Still Alive" is played in an uptempo Latin style over radios in-game. Wolpaw notes that Coulton was invited to Valve a year before the release of Portal, though it was not yet clear where Coulton would contribute. "Once Kim [Swift] and I met with him, it quickly became apparent that he had the perfect sensibility to write a song for GLaDOS." The use of the song over the closing credits was based on a similar concept from the game God Hand, one of Wolpaw's favorite titles. The song was released as a free downloadable song for the music video game Rock Band on April 1, 2008. The soundtrack for Portal was released as a part of The Orange Box Original Soundtrack.
Portal is the first Valve-developed game to be added to the OS X-compatible list of games available on the launch of the Steam client for Mac on May 12, 2010, supporting Steam Play, in which buying the game on Macintosh or Windows computer makes it playable on both. As part of the promotion, Portal was offered as a free game for any Steam user during the two weeks following the Mac client's launch. Within the first week of this offer, over 1.5 million copies of the game were downloaded through Steam. A similar promotion was held in September 2011, near the start of a traditional school year, encouraging the use of the game as an educational tool for science and mathematics. Valve wrote that they felt that Portal "makes physics, math, logic, spatial reasoning, probability, and problem-solving interesting, cool, and fun", a necessary feature to draw children into learning. This was tied to Digital Promise, a United States Department of Education initiative to help develop new digital tools for education, and which Valve is part of.
