Custom stations crashed

The custom music stations ("my station" and "discovery station") via iMusic were working normally this morning. I use them regularly.

I started the "my station" on my phone and it first switched to a shuffle of music local to my phone, then refused to play anything other than the "new music mix" for the week. When I attempted to replicate the error on my laptop it refused to play at all, gave me a "an error occurred" message which crashed, I was unable to close the error message without force-quitting apple music.

The internet in my apartment is working normally, and I can search and play songs normally, but the infinite-play option that usually follows songs and playlists has disappeared (its normally next to the shuffle icon).

Has this happened to anyone else? Is apple about to announce that these are now paid options (that would be well within my current experience with them?
