Like the two Lauras, I enjoyed Inside Man. But I loved the song from the opening and closing credits. A little research revealed that it's called Chaiyya Chaiyya and that it was taken from a Bollywood movie.
Tragically, it's only available on iTunes if you buy the whole soundtrack album, which includes such other sure-to-be-hits as "Above Your Pay Grade" and "2nd Floor Window." Damn them.
