Ever been to a gathering that so dull you wish you’d never gone? Name a great song to get the ball rolling…
My pick: AC/DC “Shook Me All Night Long”. 
Needle and the Damage Done… Neil Young
or Neil Diamond’s cover there of…?
“Domino” by Van Morrison?
Anything by the B-52’s, really.
Monty Python’s ‘Sit on My Face’ 
For dance party music:
Red Alert by Basement Jaxx
and
We Like the Party! by the Venga Boys
Cheesy, boith of 'em, but parties love 'em!
Old Beatles: Since I Saw Her Standing There, Please Please Me, Twist And Shout, I Should Have Known Better, Eight Days A Week, etc.
The number one litmus test I have found for a party:
Jailhouse Rock - Elvis
If you play this song and no one gets up to dance, call the morgue, this party is officially dead.
“Oh, the engineers have hairy ears…”
Marvin Gaye : Got to give it up
Chic: Le Freak
Wilson Pickett: Land of a thousand dances
New song to get a party going, IMHO: Outkast: Hey Ya
My personal must get up wherever I am and start moving to this song is New Order: Blue Monday
If the party can’t be brought about by blister in the sun, I will leave. Even if it’s my party.
Gordon Lightfoot’s The Wreck of the Edmund Fitzgerald.
Just kidding. Gosh, I’ve been making this joke for years - it just gets funnier every time…
Rainy Days and Mondays : The Carpenters
“Sit Down” by James always seems to get people up dancing, ironically enough.
Stray Cat Strut by the Stray Cats!
Gets them wiggling out on the the dance floor every time!
Just about anything by the Squirrel Nut Zippers will work.
What I Like About You by The Ramones.
Zorba’s Dance from Zorba the Greek worked wonders on my prome. No, really.
Also, pardon me, YMCA by the Village People. 
It NEVER fails.
Other tacky seventies disco, Gloria Gaynor included. The sheer cheese of this stuff just makes people less self-conscious and loosened up. For most people it’s hard to groove to a complex masterpiece, if you know what I mean.
Handel: My heart is inditing.
Celebration, by Kool & the Gang!
“Rough Sex”, “I Must Increase My Bust”, or “I Sit On Acid” by Lords of Acid.
Guaranteed to bring ANY party to life.
“Pick Up the Pieces” by the Average White Band.
And I second the “Red Alert” nomination.
