A Free Idea for the Folks at Pandora

I would like to see Pandora integrated with a lyrics engine.  Most people are probably going to think of some link in the user interface where they can click it and see the lyrics for the song.  Not me.  I want something much bigger.

I want the ability to exclude a song based on a word in its lyrics, preferably by frequency and/or total count.  I would love to be able to say, for instance, "don't play any song where the word California is used more than twice".  When I brought this idea up with a coworker he mentioned it would be great to only hear songs with the word "shotgun" in them.  So we'll need this feature to allow for inclusion/exclusion of key phrases entered by the user.

You guys over at Pandora get to work on this for me please.  In the mean time I'm going to check into body armor in case my coworker has a particularly bad day...
