i hope they have songs from bands like Two Steps From Hell...epic orchistral music. They did the music for the launch trailer for Mass Effect 2
The soundtrack "Moving Mountains" from Two Steps From Hell would be fantastic for the Thor film. I can just imagine some great clips from the movie with this soundtrack playing in the background.
If anyone hasn't heard of this soundtrack, here it is:
