An introduction to k-pop music genres

Have you ever wondered what the fuck music reviewers are talking about when they discuss music genres in k-pop?  When is a piece of music one genre and not another?  Are these writers and journalists just pulling these music terms out of their ass or what?  It seems that many of you in fact wonder a lot about different music genres because I get questions all the time about it.  Of course, you could look the answers up on Wikipedia if you wanted, but what Wikipedia won't give you is the k-pop connection and k-pop music examples.  That's where Kpopalypse comes in!  If you've ever wondered about how to tell your pop from your rock, your ska from your reggae and your hip from your hop, then this is the post for you!
