   9 Things to do:
  10 ¥ Radio mode makes things ugly
  11 ¥ Add other options to the menu
  12     - EQ sets
  13     - set song rating
  14 ¥ Make preferences window pretty
  15 ¥ Hot Keys
  16     - hot keys can't be set when NSBGOnly is on. The window is not key,
  17       so the KeyBroadcaster does not pick up key combos. Bad...
  18     - the hotkey classes are ugly, I didn't write them
  19 ¥ Optimize code
  20 ¥ Apple Events!
