@aral I agree that if you really want to support the artist, and own the music that Bandcamp is the way to go. As an artist myself on there it is amazing to see that some people pay € 1,50 - 5,00 per album on the pay what you want basis.
From all the years on Spotify i think we got once or twice a payment of like 25 dollars, not even covering the cost of getting your music on there in the first place.
