i guess no one really can... but just choose the genre that u like most of all and most of the time (kinda)
there's too many different genres to be able to pick one though, like the jam band scene, and experimental music, hehe, everything man! we'd need like, about twenty different polls to work it out. I put Jazz because of Miles Davis, but then that could mean rock too, and i do love rock. King Crimson, a progressive rock band, but could be classified as jazz! wooah, isn't music WONDERFUL?! jaz
I like rock, but I listen to alot of jazz and blues, so I put that. You really ought to put more genres up there.
Rock, I suppose psychedelic and progressive rock are my two favored subdivisions. Give me improvisational hour-long freak-out jams and noodling, self-indulgent 20-minute guitar/mellotron solos topped off with cosmic, pompous artsy-fartsy lyrics.
