I doubt he sat around purposefully thinking of songs that could relate to her to add to the end of the song.

Well I think he's a very clever guy and I don't think it was sheer randomness and coincidence that those were the songs he sang. I'm not saying he sat down and thought "hmmm what can I sing to make a direct dig at Britney" - I think he chose songs which related to what CMAR is about, and it so happens that its Britney.
