Problem editing...

[JohnC#WP]

I am always looking through my music collection to make sure everything is up to date, and while I was editing stuff today, I kept getting a "Can't Save", error message. Anyone know what the problem is?

I will ocassionally get one "try later" popup, or another. I've always interpreted these as some kind of busy signal, and it's always worked soon after, usually within moments.
