It depends on how the artist wants to get paid. If the artist is an independent, meaning that he or she is not tied to any label/publisher or distributor, they usually end up getting around 60% of the sale price. The other 10%-20% goes to the person selling the file, 7%-15% goes to the costs associated with running Bitmunk and the rest goes to miscellaneous fees that an ISP might add to the sale.
It really depends on how much the artist, seller and other entities involved in the sale want to charge. You can see how much is going to each entity when the transaction contract is displayed to you in the Bitmunk Download Client.
