Liberty Music Store
https://libertymusicstore.net/Buy and sell music with Bitcoin
Liberty Music Store offers a way for artists to sell their albums and songs directly to fans online. Artists can open a pop up store embedded on their homepage to a similar fashion one would sell albums and merchandise in concerts. Alternatively if one does not have a website yet the music can be sold on a Facebook page. No sign ups or credit cards needed.
