   9 Things to do:
  10 ¥ Radio mode makes things act oddly
  11 ¥ Make preferences window pretty
  12 ¥ Hot Keys
  13     - hot keys can't be set when NSBGOnly is on. The window is not key,
  14       so the KeyBroadcaster does not pick up key combos
  15     - going to need a different way of defining key combos
  16 ¥ Optimize, this thing is big and slow :(
  17 ¥ Apple Events! Apple Events! Apple Events!
  18
  19 ¥ I think I found a slight memory leak:
  20     425 MenuTunes    7.8%  8:29.87   1    56  4827   215M+ 3.14M   135M-  599M+
