That doesn't help much, I guess. The plugin will be informed every time
a playlist is created or deleted, but the (in my mind) main usage:
adding songs to existings playlists isn't covered here. That's why I was
thinking of dealing with drag&drop/rightclick signals.

I'm wondering if it takes much effort to patch rhythmbox sending signals
when the function for adding songs to a playlist is called.
