Very cool! I'm thinking of using echonest's analysis data to have smooth 
automatic beatmatching and mixing of songs, and this is an excellent 
first step to achieving that! I'll be sure to look into it, and the the 
scaletempo libraries!

When I install the plugin, however, I get:

Traceback (most recent call last):
  File "/home/eric/.gnome2/rhythmbox/plugins/scaletempo/__init__.py", 
line 127, in activate
    self.scaler.activate(shell.get_player().get_property('player'))
  File "/home/eric/.gnome2/rhythmbox/plugins/scaletempo/__init__.py", 
line 86, in activate
    self.gstelement = gst.element_factory_make('pitch', 'pitch0')
gst.ElementNotFoundError: pitch

I *do* have gstreamer-plugins-bad installed, but maybe Ubuntu Hardy has 
a version that is too old?
