bandcamp. it's turned into a bit of a community, and you can rest assured that sales go to the releasing entity (8% bandcamp fee.) as well as not shunting sales into low-return streaming.

I use it both for my musical releases and for finding new music across the spectrum.

The entities putting music on there are largely the ones making it, not some corporate entities that don't have time for fans... (itunes, spotify, all the other corporate rarified sales channels that require consolidators for even underground labels, and never deign to directly work with lowly artists LOL)
