57. Paul McCartney, "New"
The title track from Macca's latest album sounds old, title notwithstanding, but in the best way. A Beatlesque pop confection with production by retro-modernist Mark Ronson, it's got a bouncy harpsichord-flavored melody line and a touch of brass that recalls "Got to Get You into My Life." It sinks its hooks instantly, going out on some goofy-sweet scat singing that will probably linger on your palate all day.
