Lots of ENTPs are in music...
As for INTPs:
David Byrne (Talking Heads) is very likely INTP. His blog is a great example of Ne-aux: http://journal.davidbyrne.com/
Frank Black of the Pixies is probably INTP (maybe ENTP though).
These guys have been really influential on other musicians. I think their lyrics are fantastic. I like that it's not all about love & emotion.
The dude who saved the dolphin? I hope soIs the Tallest Man on Earth INFP? I could see that.
That was the best fluff news story EVER. The sheer absurdity of it MUST be connected to Ne.
