Given this very basic appearance of success, I may give you a debug-enabled build to try out and I'll just grab all your logs ... I'll make a version that doesn't actually sync for you but instead prints out what it _would_ have done (so you can see if it would have attempted to remove a tune and why).

I'd love to do that. If I'm online later tonight, hit me up on Instant Messenger and we can pound on it together.
