Great little...ahh long ass article my friend lol.
Action packed with info and your solid perspective on some of the music applications of the blockchain(s).
I haven't yet checkout out LBRY (barring when i first heard about it and wasn't too interested in it lol). IT sounds like it's ready for a second investigation.
Have a track up on musicoin, however, I wasn't too interested in that either. It has been on my list of things to revisit though.
For me, Steem seems to be the easiest, most comfortable & effective way for to output creative content. It's probably why I haven't been too motivated to look elsewhere as of late...
Hope all is well and good!
