Being able to play one's own music during a game in the past usually meant turning down the game audio and using an alternative music player. Some early exceptions were possible on PC/Windows gaming in which it was possible to independently adjust game audio while playing music with a separate program running in the background. Some PC games, such as "Quake", play music from the CD while retrieving game data exclusively from the hard disk, thereby allowing the game CD to be swapped for any music CD. The first PC game to introduce in-game support for custom soundtracks was Lionhead Studio's Black and White. The 2001 game included an in-game interface for Winamp that enabled the players to play audio tracks from their own playlists. In addition, this would sometimes trigger various reactions from the player's Creature, like dancing or laughing.
