Progressive rock (ELP, Yes, Renaissance, Genesis, Pink Floyd, Rush, Dream Theater, Rhapsody, etc.), Classic rock (Deep Purple, Uriah Heep, Led Zeppelin, etc.), Psychedelic rock (Jefferson Airplane, Ozric Tentacles, etc.), Colosseum II, a-ha, Within Temptation, Nightwish & other stuff, but not hip-hop, dance, or country.
I'm pretty open really, I haven't even included the classical stuff or the game music.
