What I really want to see is that micro payments for individual song will become mainstream. Why do you have to buy a whole album and not individual songs? They can even start pay-per-use services, where you pay 1 Satoshi per minute for instance, if you stream the song from the internet.
The Lightning Network will make things like this possible in the near future and I cannot wait for this to happen. There are multiple use cases for the Music industry and Bitcoin.
