For me it depends on what I run. If it's something "techy" (RIFTs, Star Wars) I tend to go techno. If it's something Mideval (D&D) I prefer other types of music, usually based either on animes or games I've played. Below is a very general list of stuff I tend to run, based on music I can locate:
Star Wars
Whatever SW music I have (duh), including Knights of the Old Republic I & II, Rogue Squadron, Shadows of the Empire, & occasionally the Animatrix music & some stuff from Ace Combat.
RIFTs
Animatrix
Heavy Metal 2000
Stigmata
Batman Beyond
Mortal Kombat
Robotech
Irresponsible Capt Tylor
Various game music including KoF 95, 98, Castlevania...
.. & whatever else strikes my fancy or I have on hand.
Mideval/Fantasy
The D&D OST (has a couple of tracks which're good for mood)
Various Castlevania
Mideval Baebes
Icewind Dale
Baulders Gate
Planescape
God of Wars 1 & 2
Stigmata
Various Fighting game music including KoF, Samurai Showdown
Final Fantasy Symphonic
TES Oblivion...
... as above, whatever I have on hand & strikes my fancy. :band:
