He just said that if it were to be done that way, that'd be how to do it.

I don't see the hostname field being used at all in the code, so...

The default playlist isn't a discrete playlist.  It's a special case, it 
doesn't need a setting to name it.  It'll always be 'default' or whatnot.  
It'll always get saved on exit and loaded on startup.  Doesn't matter if it's 
an exact duplicate of another playlist.

In fact, how would you handle playlists containing other playlists with that 
schema?  I had just planned on making playlist ids negative ints inside the 
existing list.  So, a playlist of '64,23,-6,24' would be translated to 'song 
#64, #23, playlist #6, song #24' on load.
