It's not that I think it would unjustly drain the reward pool. A rising tide raises all boats, after all. It's that Muse may need to employ an entirely different sort of economic system / rewards structure to function as intended, one that Steem might just not be able to accommodate without drastic changes.

I don't know how it's going to look exactly but let's say hypothetically that Muse will reward artists for each second that their music is streamed. In that case every second you listen to a track is treated like a kind of vote for that content. That is just an entirely different way of going about allocating rewards for content. And will rewards be distributed relative to stake? Or will 'each second listened' be treated equally regardless of who is listening, whether whale or minnow? I don't know how they're going to do it but I suspect it could require an entirely different sort of economic engine to achieve the desired result.

I'm just speculating, it will be really interesting to see what sort of system they employ.

Thanks for the heads up on the peerplays / peertracks mix up! Maybe that's a signal that one or both need to rebrand ;)
