Tip o' the iceberg is right.
I would like to see a way to leverage Steem & possibly Steemit to enable musicians to make a really good living by posting their work. I know there is work on Bitshares Music (Peershares?), and of course Bittunes has been functional for a while. But there is appeal is doing it very simply... just cross posting YouTubes of new original music to Steemit would probably be hugely more profitable to artists.
