DRM probably isn't necessary. We mostly need a legal and cultural structure that recognizes you should pay for recordings (and outlets that let you do so easily). There'd be some leakage (as there's been as long as there's been consumer recording tech), but people know the difference between participatory patronage and mooching, the market would provide a way to choose and do both. And perhaps the biggest threat to this is buffet streaming services like Spotify, which give the veneer of legitimate participation and remove incentives to buy, but reduce the remittance to artists to a vanishing fraction of what recording purchases can provide.
