Nobody that I know of. At this point, there are very few people in the valueverse in general, so it doesn’t really make sense for artists to join in order to get some reasonable value back.
The only reason to join would be if the musician is a Bitcoiner/Nostrich.
I talked to some of my musician friends about it, but aside from ideological reasons, there’s really nothing to argue with. It would be just another platform (and let’s be real, not a very user-friendly one) to take care of.
I think the ball is in our court, though. We don’t send enough sats to make this work. It’s not the artists’ fault.
