Wouldn't a tax on paid downloads to fund a dollar matching system just discourage paid downloads even more? I think the entire premise here is that paid downloads of any kind are going to die and the only time you have scarcity and therefore can charge money is before you've created the art.
The concentration of power is a good point, it would be best to have a healthy ecosystem of Kickstarter clones or at least some model that avoids a single "hottest projects" page, those damn things bleed money from everyone else to create blockbusters.
My point is that there will probably be services beyond simply giving me music that I and people with similarly inelastic demands will be willing to pay for. Whether that manifests as a Spotify-like subscription or iTunes-esque pay-per-download has yet to be seen.
Ah, gotcha. I see those services dying pretty quickly actually and music just being shared and downloaded from all over and always free.
I guess there will always be a place for pay services dealing with recommendation or cloud storage but I'm assuming that the value of a digital copy of a song, streamed or not, will be zero pretty soon.
