It'd probably be a bit less winner-takes-all without the capitalist dynamics that make it such.
The technology plays a huge role.
Why watch local soccer in most of the world when you can watch the Champions League on the internet ?
In the Soviet Union people were watching Dynamo and Lokomotiv on TV rather than going to local games too.
I don't think the capitalist dynamic have as much of an impact as the technology and social factors.
Tech allows distribution, and the social factors is people want to listen to what's popular
The problem is that it's a bit of a winner takes all market. It's comparable to professional sports.
Everyone loves soccer, but 99.9% of people won't get paid to play it. That doesn't mean it isn't valued - some of the highest paid people in the world are soccer players!
