Peter Hajba, a.k.a. "Skaven"'s "Data Jack", the music for time trial mode for the first Bejeweled game... think "boss battle" but for a puzzle game. At one point, the main theme (though purely instrumental) sounds like it's singing "fucking war-cow".
The main soundtrack of Bejeweled 2, collectively called Beyond the Network by Skaven, is 41 minutes of pure videogaming music euphoria.
Bejeweled 3's soundtrack, which was co-authored by Skaven, also has some pretty awesome tracks. Instead of having one long track like its predecessor, this game features shorter, game mode-specific tracks. Some examples: Ice Storm, Lightning and Diamond Mine.
