I kind of go through these phases where I listen to a certain kind of music, but then I find out about a bunch of different bands in a different genre and I get into that, discarding my previous phase. Here's an obscure example, a couple years ago, before I listened to most of the stuff I listen to now, I sort of went through this hair metal phase where all I listened to was people like Ratt, Europe, Autograph, and Van Halen - but that was before my music taste really developed.
Right now, I'm really enjoying artists in the Britpop, IDM, electronica, 60's British Invasion, and 90's indie pop genres.
