Since I'm a fan of finding real life examples of types, let's talk about some musicians. I'll post my opinions, but keep in mind that this is in no way definitive; I hate definitives. Some people keep on forgetting that right away, and criticize automatically with out giving any reason. Ok, here goes;

Bob Dylan- INTP

Elvis- ESFP

Anthony Kiedis- INFP
Flea- ISTJ
John Fuscante- ENTP?

Van Halen- INFP

Billy Joe- ENTP

Mick Jagger- ENTP
Keith Richards- ISTP

Kurt Cobain- INFP
Dave Grohl- ISTP

Cedric Bixler- ISFP
Omar Rodriguez- ESTP
Jon Theodore- ISTJ
Flea- ISTJ

Jimi Hendrix- INFP

Micheal Jackson- INFP

Eric Clapton- ENTP (J?)

Freddy Mercury- ENFP ?


I think that's a nice start.
