I think that generally music should be a positive thing, I like Bob Marley's attitude: he said that his goal in life was to single handedly fight all the evil in the world with nothing but music, and when he went to a place he didn't go to play, he went to conquer.
“I write the music because I can't really write lyrics. But I can write chords like Robin's never heard of. So I provide the music for them to add the lyrics to.”
