I generally like any genre, favs would be alternative rock (Radiohead, etc.) and whatever Bjork is, ambient I suppose. I like hip-hop for the beats but not so much for the lyrics which, let's face it, have just become lazy. I like 90's/00's music mainly as I grew up with it, but also like 60's and 70's music too (Beach Boys, Zeppelin, etc.) I don't really class what I like by genre, I class each band on it's own individual merits.
