Intermittent problem playing back music: no permission to access requested resource error

When using the Apple Music app for iPhone, especially when on a cellular network but sometimes also on wifi, I have problems playing any given song. The problems are:

• app doesn't start playing song when selected
• app starts to play song and fades out or stops in a few seconds
• app presents error "You do not have permission to access the requested resource."

The problem persists after closing and re-opening the app several times. Other songs will typically play back after this happens, but the song where the error starts is stuck in that state for a while.

The songs are almost always through iTunes Match.

Any suggestions for how to fix this, or a fix from Apple since it does seem to be an issue on the server side, would be appreciated. Thank you.
