Even without physical media, I'd rather pay for a copy of the music I can "own" (I.e. like a physical CD) from Bandcamp as the revenue the artist gets is _significantly_ higher than a dozen streams of the same album on Spotify.
At the end of the day, I want the artist to continue producing music, and prefer to find a channel by which they get the most revenue.
IMHO Bandcamp is one of the best things to happen to the music industry in the last decade. Love it!
