The biggest issue I have with non-playable songs is with the Disney Tangled album. I can't play any of the songs sung by Mandy Moore or Zachary Levi on that album. They appear there but won't play when I click on them. The score and the songs sung by Donna I can play but not any other ones.
I've tried reinstalling but I've had this problem over multiple devices for over a year now. I recently found out that one of my friends can play the songs without any issues so it seems it's only a problem with my account.
Couldn't find anyone else in the community who has the same problem but if anyone knows how to fix it, it'd be a huge help! Would love to be able to sing to my heart's content once again! Thank you!
