I've never really listened to SOAD, and I don't wish to these days. I don't even listen to Metallica anymore. I prefer the positive and more relevant messages of Christian music.
Anyway, I read something that described in non-MBTI terminology that the most creative people are NPs. I concluded Mike Patton is an ENFP, and he certainly wrote a lot of random, creative, unusual stuff in his various bands (Faith No More, Mr. Bungle, Fantomas). Just a guess, but Les Claypool of Primus is probably one of the NPs.
