jquery (ajax) post to controller to model (and back) to view problem

To find out what is actually happening when you click on the link, open up Firebug's "Net" tab.

In your jQuery code, first argument for $.post is supposed to be a link, "change_lyrics" is not a link. You don't have 3rd parameter for $.post, so even if you get data via ajax, you don't have a code to handle this data.
