Apple Music stuck loading after resuming playback on MacBook Air

I yesterday listened to an album and afterwards Apple Music kept on playing "similar music". I paused it for a night and today resumed but after a song this darn thing is stuck at loading.

I was thinking maybe developer didn't realize people might kept it closed on the night and resume next day and it's some kind of session problem. Or the session problem comes from server or firewall.
