"Hello Mr. Ethir" by A.R. Rahman is my current SOTM. Funky bassline, catchy, and provides a happy blend of American jazz and Bollywood pop sensibility. It's fast-tracking its way to becoming a favorite Rahman song (and that's no mean feat.) If Slumdog Millionaire's soundtrack was considered a "phoned-in" effort by Rahman fans, then the guy's the greatest film composer in the history of film composers.
