Apple Music saying content not authorized

The other day I was listening to a song and it worked. I tried to listen to it again a few hours later and a pop up would show saying “Content is not authorized”. This has never happened before on the version of iOS I was on (iOS 14.6). I thought that I had to update my phone to 14.7 but it still wouldn’t work. I decided to play it on my Apple Watch and it worked. Is there anyway to fix the “Content is not authorized” pop up so that I can listen to the song again?
