I could see there being some kind of community once they are created for bands and music creators. I think it would be kind of cool. Sort of like a blockchain based MySpace. Since that is what MySpace was originally created for anyways. The problem is still getting people to join, but if they tied it in to their "fan club" which lots of people join via email anyway, it might work.
It just needs some to take a chance on it. The band I mentioned are aware, but they responded to a tweet saying they have not had a chance to look into it.
Oh wow, that is pretty cool. You are right, there has to be someone that has a personal connection to some bigger band that could break the ice with Steem. Perhaps @verhp11 knows someone :)
