You can actually do something like this today, without writing a single line 
of code. Here's how:

- Add a new panel (whereever you want it)
- Set it up to autohide
- add the now playing widget to it

The Now Playing widget uses the MPRIS protocol to talk to a number of media 
players. If yours implements this protocol, it'll just work.
