Do you also have an option inside Conky for controlling music playback? I really like Covergloobus, you should really try Clementine, it works just as good.
I wouldn't know where to begin to write something like controlling music from Conky. Some of the gurus in the Conky Thread at Ubuntu Forums or the Crunchbang Forums might know.
I have used Clementine, I just prefer Audacious' simplicity.
