Sounds good. I just had a look at the current state
again and I think we came to a good solution.
Looking forward to JSPF v1 in action!

One more thing: I stumbled over these single lines on
the XSPF.toJSPF() page:

  duration: null
  trackNum: null
  album: null

To me it seemed logical to map '"key" : null' to an empty
tag '<key></key>' but what does '"key" : ""' map to then?
So '"key" : null' is equivalent to omitting that element?
