A somewhat random question comrade. What makes you think I think he's a dickhead? He is, or rather was, an immensely talented guy and such dudes tend to be complicated personalities. He'd written 3 of the best albums of the 90s by the time he was 28!
That said the new triple album he just dropped is shite.
