Hey, I'm really excited by the biased playlists that Amarok 2 has, and was interested in implementing some biases myself.  I've got the Amarok source, but I'm not sure where to put the source for the new biases and how to hook them in.  Are they implemented in C++, or are they scripted on top of Amarok?  If so, what scripting language is used?

Thanks for your help!
