I can't listen to hip hop. Or anything like rap or pop that is so simple. I don't care if it has a "good beat," you have no idea how boring it is. All of Beneath the Massacre's songs have a great beat, it's just not in 4/4 with a 2 part chord progression, so you won't listen to it.
I said ISFJ, because my dad is an ISFJ and he's about the last person in the world I can imagine enjoying hip-hop. But I really doubt there's any correlation here... hip-hop is such a wide genre, too, I'm sure there's something for people of every type.
The only music thread I frequent is in the INFP forum, and even there there's a huge range of genres--hip-hop, classical, rock, metal, everything. I just don't think musical taste can be determined by type.
It's really hard to say. I'd say a J type, since most of the J types are too busy to listen to hip-hop or they judge it too quickly...but those that DO like it would probably listen to it more religiously than a P would! So it kinda balances out. ^^
I think musical preference mostly depends on environment, like what you're exposed to. Like big gapes in genre are possible. Some like things technical and abstract and others like it straightforward and catchy. Not saying those can't intertwine.
