'Keeping requested music' takes forever?

Hello all,

This has been a problem for a while now, and with today's Music update I wanted to give it a whirl after a hiatus. However, the problem still persists -- it takes forever to pin music to my device, whether I'm on data or WiFi. I've restarted my device and unpinned/repinned but to no avail.

Any suggestions? It's an otherwise nice update and the streaming service is interesting. I may switch from Rdio for the price drop alone.
