Here are some more I have noticed because all of my friends are NTs (I like all this music too of course, otherwise I would not have remembered it):
The ones I put in bold are ones they all have in common with each other:
Explosions in the Sky
Death Cab for Cutie
God is an Astronaut
Fall of Troy
Rodrigo y Gabriela
I have also noticed NTs are really fond of math rock and electronic music.
I can't think of anymore right now...
