I am still on the fence about MUSE.. I haven't purchased any tokens yet. I don't rarely invest in vaporware (I didn't invest in BitsharesX pre-release either), so I am waiting to see if they can deliver what they have designed. The design seems like it could be a profitable/popular blockchain service, but I am not sure how big it can get. I think adoption in the music industry and/or consumers (ironically.. similar to the DEX) will be a tough hurdle to jump.
