Okay, I'll try that. The thing is I'm sort of new to Amarok development 
(I only worked on the podcast part before) and it's a bit difficult to 
understand the playlist part. It would be much easier if someone could 
update this page http://amarok.kde.org/wiki/Development/Architecture. 
Would help others as well.
