Janelle Monae has launched an app designed to clean out your Spotify playlists and replace them with something better - her album.

"Feel what it’s liked to be cleaned," Monáe wrote posting the app on social media.

It's a bit of a gag but basically what you do is pick a playlist that you've made and it will automatically clear that playlist and replace it with her new album Dirty Computer.

Be careful which playlist you choose because you're not going to be able to get it back. That said, Dirty Computer is the best album of the year so far so it should be in all your playlists anyway.
