I have a broader concern for how new artists are supposed to get discovered without a promotion engine behind them. Yes it's always been hard to get started, but the distribution of attention has really become much more top heavy in recent years. I know one guy who played Wembley stadium and still couldn't give up his day job which he was sure he would have been able to do following a gig of that size in the 90s. Yeah so he had a good number of monthly listeners, but it illustrates how the distribution has changed.
Plenty of people on the long tail deserve to be discovered, and use of AI to recommend music - in place of collaborative filtering - really has the potential to fix that.
PS. We were talking monthly listeners weren't we, so you'll be excited to know that fractional fans exist already ;-)
