If you are contributing in Missions on our Musixmatch Studio, please note that Spotify Premium plus Google Chrome browser are now required for full functionality.
The ability to work Missions will continue to be free, but you will need to upgrade to Spotify Premium going forward.
Verify that you're connected with your upgraded Spotify account when you log in to Musixmatch. You may have to log out of the app, then log back in prior to launching Spotify.
Sometimes, you may also meet problem like ‘Spotiy won’t open’, here is the solution.
