Please please please put it up for sale. Or download. Or something. It is some of the best background music I've ever heard. It's catchy, but not too catchy. It's fun, but not too fun. I actually find myself idling in game during work because it's as good or better than most of what I usually listen to while working.
And it's still perfect for playing! Y'all have done a great job matching the tone of the game & regions with music. Someone planted the seed in my head that the Uralia music is Hotel California on Purp... which is exactly as the music there should be. The swamp music is just murky enough and the music in the ancestral lands... well, you totally outdid yourselves there. It plays perfectly to the sense of urgency you have when running through there and I can't help but grin and bounce as I go. It's just perfect.
