- Bandcamp - a bit off-topic but the music industry has become an exponentially distributed winner-takes-all game. I resist by buying underground music on Bandcamp - it's an exemplary web platform, gives generous cuts to the artist, and you own the files. Even if I only listen to the song a couple times it feels good knowing 80% of the money is going straight to talented artists and 20% is going to a beacon of hope on the internet. Money spent on Bandcamp feels good.
