Christmas app transpose still not working

Latest version says transpose should work now, but it doesn't; in fact it seems more broken than before. Still a cool app, though!

Oh yea, instructions to reproduce: select first song (angels...), hit up arrow, then down. Should return to original key of F. But instead key signature reads G, and accidentaks are used to make it F. Others issues too, but that's the most obvious way to see a clear problem.
