Here is my idea: Everyone makes a private key. When they buy a song they receive the file and a digital signature by the label saying they sold it to your private key. When you are caught with a bunch of songs, you have to prove ownership using your key. Tadaa provable ownership, no blockchain, You loose the file, but still have the signature? You can download it again and all is good.

A digital signature from the label would be created with their private key.

What would they be signing? Your public key plus the ID of the song? They can't sign your private key, it's private.

What stops you sharing your private key and a song with a friend. Then when either of you need to provide proof, you can both show that you have the private key that matches the signed file?

But what if you still have file, but lose the signature?

Well if the record label was still around they could make ownership details public, or let you download the signed file again.

How would they know the copy legally belongs to you if you lose the key? Would they require some form of ID on top of that?
