Music, like most other arts, has always kind of been like this so far though. You make no or very little money and are kind of struggling along unless your famous, or at least underground famous. But in recent years (much like the trend across societies in general) this discrepancy has intensified, I recently read some Professor describing it as the hollywood effect; meaning: fewer people make more money and most poeple just dont. I think Blockchain technology and platforms like peertracks and muse or musicoin, at the very least create the possibility for much more even distribution and hopefully artists with a smaller but dedicated fanbase will also be able to pay their bills.
