NLC  nix previous post. It's still not loading the majority of songs... at one point it froze, and after restarting it, it won't even respond to iTunes... just does nothing. :

NLC  Had an issue with the last version where it stopped updating songs after a while and just stuck forever on 'Loading...' I'm not sure if it's fixed in the new version yet, but we'll see. So far it's working _mostly_, though there are some pretty popular songs that it can't find lyrics for, and when trying to paste the correct lyrics in, it fubars the text so it's unreadable (all posted on 2 lines, then over itself for multiple lines).
