I don't listen to music beyond the soundtrack for most games, usually when I do its multiplyer or a game like X-Com or M&B.
If its multi-player or something I need to concentrate on music with no or minimal lyrics (generally, there some songs and styles with lyrics where that's fine). If I'm just messing about any music I'm in the mood for that isn't specific to gaming.
Sometimes it will be thematic music. If I'm playing fallout 3 for example I just want more of he sort of music they already have in the game.
