Play Music keeps stopping for no apparent reason

Hi,

I'll be listening to music on my Pixel and Play Music just stops in the middle of the song. It doesn't visually look like it's stopped, because the "Pause" symbol is still displayed as if the song is playing. It goes totally silent for a few seconds, then I get a light "pop" sound like it's trying to do something, then more silence. If I hit pause, then wait a second or two, then hit play, I get the little orange circle like it's trying to re-download the song, and usually the song starts back up after that. It's annoying.
I had a help call with Google and they had me clear my caches. That does not appear to have fixed it. Any ideas?

Please help.

I didn't find the right solution from the Internet.
