Blockchain is excellent for digital rights management, I just wrote a technical post for non technical people which calls for long term upvotes of special content like music, because you don't want @Cheetah do remind you that you're spamming!

Steemit allows just for 7 days for new content to be curated and thus monetized. Other people could resteem or upload your music to earn curation but that means you'd want also tracking of your music and it's remixes to get a piece of the pie!

And last but not least, what about the #muse project? I was hoping it would solve this problem, and I'd love to make riffs, drum-loops and other cool parts people can use in their music.
