Those are some really beautiful pieces of music. Quality music like that is actually quite rare on the marketplace, though I’d buy it in a heartbeat if it were up there as I have with the others I managed to find. Loopable songs would probably be of more use to developers too as they can be utilized in environments. I hope to see products from you in the future, great work! =)
You might also want to post this in the marketplace forum for better exposure around this subject. Maybe a mod can move the thread for you.
