its sort of like a book.

i was talking to this kid the other day about this band he was trying to start. he was talking about how he wants to talk to the other guys about what style they are going to be playing, so he can know what to write about.
if it sounds like Cannibal Corpse, he would write stuff thats just gory.
if its thrash, its gotta be politics.
and so on.

but i proposed, that music is like a book. you can make it say, whatever you want.
