Not going to read through the entire thread. My husband is 32 and listens to Death Metal (oh how I HATE his music), and he is brilliant and not the least bit violent. my oldest and youngest sons are not very into music. My 9 y/o, however, is. He has a rather large collection of "crap" according to what I am reading here. He is also at the top of his class in all subjects, will be in the math carnival, is well behaved, reads constantly, is polite and just too stinkin' cute. Music is NOT what makes the person.
