Spotify is a great platform for users who enjoy listening and discovering smaller and independent artists. However, many of these artists are not earning a great deal from Spotify streams. As a result, I would like to see an artist donation option for all artists registered with Spotify. If you discover smaller artists and wish to see them continue to make music you can donate to them via Spotify. Spotify already has credit card/PayPal info and can transfer the money from the same payment method used for the account.
Spotify would presumably take a cut of donations for work required to process payments.
