  Log Message:
  -----------
  A few more improvements to the music API
- Handle all plausible cases of assigning into the playlist
- Allow changing the current track to an existing one on the playlist
- Allow getting playlist as a real array instead of an array-like proxy
  (Could be useful for storing it to a WML variable, for example)
