It's kind of hard to guess this sort of thing, given that we're given no indication of the kind of books/films/TV series/music any of the characters like. You also have to remember that the books are set in the 90s. Also, since Ginny is a pure-blood, I'm not sure how much exposure she'd have to Muggle entertainment.
