If you plan on doing label releases, DistroKid is the way to go. From my label experience some/most labels use DistroKid for distribution. Not sure how that would work with Amuse.
Also, you can get a huge discount from DistroKid if you sign up and wait 24-48 hours for them to send an email giving you a discount. Wait a little longer got another email giving you a better discount, and boom you get like 45% off.
