Recognizing UI Changes done with jquery in c#

I have a playlist that allows users to drag songs away from the playlist to drop box so that can work with a long playlist.  Users can also search our DB for other songs and add songs to the playlist, but this is done with jQuery.  how can i get the changes to the playlist done with jQuery to be recognized in c# server side sorting.

this is a related post where i learned how to get jQuery to work after and asp.net ajax call: http://forums.asp.net/t/1626678.aspx & http://stackoverflow.com/questions/4268322/asp-net-ajax-jquery
