He's 15. Been mad about it since he was about 10. Its on nearly all the time, even when he's doing homework. I have made him keep it low in terms of volume, but it seeps through our small flat sometimes, this dirgy, negative monotonous beat, plus the whingey, angry lyrics, the swearing and generalised, for want of a better word, hatred. I've always loved all kinds of music but this is all my son listens to, which I think is sad, it seems to me all so angry and down on life 
Can anyone shed any light on this? AIBU?
