Is there anywhere to find the music in this game, like what some of them are called? Like the warden kreig music was so badass, but I have no idea how to find the good soundtracks in here. Is there any way to find them?
You can get the game soundtrack with one of the upgraded versions. I have never opened it up to see the names, though. 
If you google “Grim Dawn Soundtrack” it actually supplies a list of names, you could try to do some deduction from there.
