dedications

i currently running a broadcasting station using shoutcast. I would wish to add a dedication service for my listeners. i.e. when they click on the particular mp3 they want to dedicate thru my homepage it would enqueue into "my" winamp playlist currently broadcasting on my server AND not playing on the user own winamp OR load a new winamp on my side thus resetting my playlist. I sort of getting nowhere in this, pls help.
