Music App Fails to Load Library from Apple Music

Sometimes when I run the Music app after a restart, after a few minutes it will tell me it can't load my library from Apple Music. As a result, most of my songs, if any, show up or are made available, no playlists, nothing. Quitting and reopening Music doesn't help, it all loads on my other devices without fail (iPhone, iPad), and my Internet connection is fine (I can browse, stream, play online games, etc.). Another restart rights it, but it will still happen again eventually.

Sadly, Google, Bing, and DuckDuckGo have failed me in helping me find anything on this.

What could be causing this? How can I get it to work again without restarting it (is there a process I can kill and restart, for example)?

Thank you, folks.
