A couple years ago (when I was 13-ish), I listened pretty much exclusively to John Williams and a couple other film composers. I found most classical/romantic/baroque/modern music boring. What really broke me out of this was joining an orchestra and playing other types of music. I also think that you learn to enjoy what you listen to. I used to dislike Copland, but someone gave me a CD of his music and I began listening to it. Now I really enjoy his music. So, my advice is: Listen to other music and you will probably start enjoying it. I don't think there's any need to "ban yourself" from listening to Bach (I still listen to John Williams quite a bit), but don't listen exclusively to Bach and you will grow to like other music. I think. Maybe.
