Things to do:
¥ Radio mode makes things act oddly
¥ Make preferences window pretty
¥ Hot Keys
    - hot keys can't be set when NSBGOnly is on. The window is not key,
      so the KeyBroadcaster does not pick up key combos
    - going to need a different way of defining key combos
¥ Optimize, this thing is big and slow :(
¥ Apple Events! Apple Events! Apple Events!

¥ I think I found a slight memory leak:
    425 MenuTunes    7.8%  8:29.87   1    56  4827   215M+ 3.14M   135M-  599M+
