   2 Things to do:
   3 ¥ Radio mode makes things act oddly
   4 ¥ Make preferences window pretty
   5 ¥ Hot Keys
   6     - hot keys can't be set when NSBGOnly is on. The window is not key,
   7       so the KeyBroadcaster does not pick up key combos
   8     - going to need a different way of defining key combos
   9 ¥ Optimize
  10 ¥ Apple Events! Apple Events! Apple Events!
  11 ¥ Upcoming songs menu items are disabled after launching iTunes and playing
