The Portal Soundtrack is available as part of Valve's Orange Box Original Soundtrack release; which includes the music from Portal along with that of Half-Life 2: Episode One, Half-Life 2: Episode Two and Team Fortress 2. In addition to the game's version of Still Alive, featured during the credits, the Soundtrack also includes a mix of the song with vocals by its author, Jonathan Coulton. In September 2014, to celebrate the release of Steam's Music Player, Valve re-released the Soundtrack for Portal as free DLC available to those who own the game. __TOC__
