I love the music in this game, too. Very unique, ambient stuff. I really like all of the music, but if I had to pick just a few favorites, I'd say I like Phendrana Drifts (upon your first visit), Magmoor Caverns, and the Space Pirates fight music. The music for Phendrana Drifts is just so relaxing and beautiful, really, and I always find myself bobbing my head when I venture through Magmoor Caverns and, lastly, the Space Pirates fight music is pretty intense and goes nicely with the awesome shooting battles you get into with them.
