Personally, I like a bit of everything. I actually mean everything too.
I've noticed a bit of anti-rap here, but try listening to a group called Sweatshop Union (try too look out for a song called "The Thing About It"), these were the guys who certainly changed my opinion on rap music.
I also listen to a bit of dance/drum and bass when it suits my mood (usually riding street BMX), and I'd definitely say The Prodigy hold top spot for my favourite band in that genre.
I've got the odd bit of orchestra I listen to, a bit of ambient...well, a fair bit of ambient and I love my Bob Marley.
On the other end of the scale, I've got a fair few "Hardcore" gigs under my belt now. Bands such as Eternal Lord, Everytime I Die and Bury Your Dead.
I LOVE At The Drive-In and the whole experimental Post-Hardcore scene. Bands like Yourcodenameis:Milo and iForwardRussia! are fantastic.
I also listen to some softer stuff such as Fields and The Automatic (well their new stuff anyway since they got rid of the yelping guy off the first album).
I've got a special soft spot for Deftones too, for some reason I just LOVE them.
Oh, and a special mention goes out to Winnebago Deal for being THE most intense live band ever. There's only a guitarist and a drummer, but they can easily leave your ears ringing for a week. Watching them in a small intimate venue is pretty much like being locked in a room with two VERY pissed off wildcats. Just check this live video out:
