Who cares if you end up liking Beyonce and Ke$sha, if you enjoy it then you enjoy it, that's all that really matters.

Maybe you just need to find something new to listen to. Sometimes I get bored of a particular band or genre, and I enjoy it more after I've taken a break from it.

I can give you some recommendations if you want, I don't really like metal but I listen to a lot of punk.
