Probably, I don't know them well enough, but I'm certain msg_v2 is wrong, whether it was a joke or not.
Sure, go ahead and ignore the mountains of evidence otherwise.
Sure! INTJ in my oppinion, just listen to his score from the Social Network.
That makes sense. I do think he's NT, but I don't think he's INTP or even ENTP. Ti doesn't really show through. I also think someone with Ne who made it in the music business would have developed it to the extent that they'd be more playful. I see Ne (and Se also, I suppose, but in a different way), as very playful. There's a level of seriousness to his work that I can't see any NTP musician possibly having. Maybe that's Fi earnestness coming through?
