If you are using Apple Music for your "Team Songs", and you run into an issue where the music stops playing after 30 seconds (song sample), the reasoning is usually one of the following:

  1. Your Apple ID isn't logged in anymore
    Go to TEAMS > Select a Team > Re-Authorize your Apple Subscription.
  2. Your subscription to the Apple Music service has expired
    Double-check that you are still subscribed to the Apple Music service.
