The Half-Life 2 soundtrack was composed by Kelly Bailey. It is an amalgamation of newly-composed music and several cues from Bailey's previous work on Half-Life. Most, if not all, of the tracks were named by Marc Laidlaw.

The limited edition Half-Life 2 "Gold" package included, among other exclusive extras, a CD soundtrack. Although the CD contains several exclusive tracks, it does not include all of the music heard in the game. Using an appropriate program, it is possible to extract all audio tracks heard in-game from the hl2_sound_misc_dir.vpk archive file. The soundtrack (save the CD versions of tracks 1 and 34) was also included in the game directory of both the full and demo Audiosurf releases on Steam. On September 24, 2014, the soundtrack was made available as free DLC to all owners of the game on Steam.
