I don't it's a genetic thing.

AFAIK I like more genres than I don't, but everything I've ever gotten into (Rock -> Metal -> Jazz -> Hip Hop -> No Preference) has been because I've convinced myself to like it. Possibly a genetic trait but it doesn't feel right, especially given that metal music can be appreciated for totally different reasons: One doesn't listen to Opeth the same way as meshuggah
