Are you a conservative insurgent looking for an election-night jam? If so, get a hold of “I Gotta Feeling” by the Black Eyed Peas. It was played as the balloons fell in Boston during Scott Brown’s victory party and throughout Christine O’Donnell’s Dover bash last night.

Other popular tracks at O’Donnell HQ? “Tubthumping” by Chumbawamba was a hit, with its famous chorus: “I get knocked down, but I get up again / You’re never gonna keep me down.” So was Journey’s “Don’t Stop Believin’,” along with its opening line: “Just a small-town girl, living in a lonely world.” Aerosmith’s “Sweet Emotion” was another favorite. Bruce Springsteen, too.

As Paul Begala once told me, a campaign “is like a film — it never comes together until it’s scored and tracked.” Indeed.
