Lots of love for good rap here I see. ^^ That pleases us.

Rap/Hip-hop
J-pop (mostly anime OST's and stuff)
Ambient techno (I think it's called)
Symphonical (Also mostly in OST-form)

Pigeon John
Jedi Mind Tricks
Immortal Technique
Atmosphere
Jurassic 5
Mos Def
Pharaoe Monch
Talib Kweli
Squarepusher
etc.

Not listing soundtracks and stuff since it's so sporadic. But I loved the soundtrack to The Rock as well as various intros and outros to favourite anime's. =)
