Two points especially pique my interest:

>to the professional music business the 7 day monetization window that Steem blockchain enforces is very limiting, ...

and

>a pay per play or attention based monetization approach as well as other licensing possibilities come much more interesting, as the works remain monetizable and licensable forever, with direct and realtime payment of rights and license fees from the user to the author.

I.e., removing the non-creator middlemen (plural) from the equation. Forever.
