Spotify beta testers are essential to help bring users the best experience by working out the problems with Spotify across multiple platforms. However, beta testers receive nothing for the vital work they are doing.
I realize how vital beta testing is for Spotify. However, beta testers receive nothing from problems they help find or solve. I think it should be required for beta testers to receive an incentive in return for their vital work. This incentive could be as simple as free Spotify Premium while they are part of the testing program.
Beta testers are crucial to the Spotify platform and need to be treated as such.
