He's a great recycler. The wider my experience gets though (i.e. the movies I watch or books I read) the more i realize that he just grabs things that are already done and puts a little twist on it. His song lyrics suck too.
J's got me into a Kiss phase right now and their song "Within" (which I really like) reminds me so much of a Zombie song. It's either House of 1000 Corpses or another one I can't think of the name of. I'll have to play it and find out which one exactly.
