You could do some anonymous block-chain ledger type-service, really doubt that it would win over simply bit-torrent though, and ultimately I'm kind of biased since I really would prefer that real creators get to exercise their rights.

What is this blind obsession with "THIS NEEDS A BLOCKCHAIN!!!!!!!"? There's nothing, absolutely nothing, in a system of storing playlists which needs decentralized canonical ordering. A blockchain is literally one of the most inefficient ways of storing data imaginable, and serves no purpose here other than a buzz word.

Some people have never heard of a DHT, and think that "blockchain" is a workable primitive instead of a high-level tool. It's like immediately jumping to "let's create a table for that in Postgres" instead of first considering whether the problem could be solved with a dictionary.

Also, if people are looking for something to use as a primitive, I'd much rather they look at Freenet. :)

No, there is something. You could use the blockchain as a decentralized torrent tracker.

Why on earth does that need canonical ordering.

It's not about the canonical ordering. It's about storing the pointers to files in a way that cannot be taken down by authorities. The playlists themselves could be stored anywhere, including but not necessarily in the blockchain.
