More of a heads up and a gripe than a support issue, but this was incredibly annoying to wake up to.
Last night, Spotify updated itself. This morning when I fired it up before hopping in the car for my commute, I was greeted with a progress bar: "0 out of 1016 songs downloaded"
I have no idea what in the recent changelist would invalidate the download cache, but this is not a thing I would expect to happen with a Spotify update.
It's frustrating to me because the app in general has performance issues, and these issues are exacerbated when the app is downloading songs. As such, I didn't use Spotify this morning (streaming to my 3G phone has lots of problems, which is why I keep playlists offline!), and I'm considering turning updates off if this sort of thing is going to keep happening.
