Spotify is getting ready to enable a block feature in its apps to mute artists you don’t want to hear from. Spotify is currently testing the “don’t play this artist” feature in its latest iOS app, and The Verge has been able to test the new block functionality ahead of its release soon. The feature simply lets you block an entire artist from playing, so that songs from the artist will never play from a library, playlist, chart list, or even radio stations on Spotify.
