Took my iPod into the Apple Music store for a battery test. PodWorks found all the 'deleted' songs they put on it for a test, now I have 6 gigs of new songs ;-) Which I of course trashed immediately. I don't want iPods to get the reputation of being only for pirated music.

But seriously, great for keeping my work and home computer iTunes libraries synched. Other tools like this work, but they're really slow for some reason.
