When I add albums to my Apple Music library on macOS, they don't immediately show up in Longplay. Sometimes mashing the "Refresh Library" menu item works, but most often I have to quit Longplay and re-open it in order for the library to properly refresh.

This makes the workflow from "Oh I'd really like to listen to that new album" to "I've now got that album queued up in Longplay" pretty slow.

Action:

I add an album to my Apple Music (streaming) library

Expected Result:

The album shows up instantly in Longplay. Alternatively, the album shows up as soon as I refresh the library using the menu item.

Actual Result:

The album does not appear in Longplay until I quit and re-open Longplay.
