How do I delete a Spotify radio station on iOS?
You can't. The Spotify app for iOS provides free streaming radio service for anyone with a data connection. Selecting a genre, song or artist will play similar music and create a radio station under Your Stations in Spotify Radio. So what if you create a Spotify radio station and want to remove it from the list?
Once created, radio stations in the iOS Spotify app cannot be deleted. As of the current release (version 0.9.0.8) there is no way to remove or hide a radio station after it appears in Your Stations.
