IMO, bits no; license yes. It seems to me that an argument could be made for the fact that you entered into a binding contract. In exchange for the money you tendered, you received the license to play the music. The bits is simply the tool by which the license is utilized. So unless the fine print specifically dictates that the license terminates upon the death of the license holder, I would think a lawyer could successfully argue that your estate possesses the licenses. And I agree with you, the difficult part would be the subsequent actions; what is the value of these licenses, and how do you sell a license that consists only of bits?
