2010 had some great jams, and all week, MTV News has been counting down some of its best. Everything from Lady Gaga's "Telephone" and Rick Ross' "B.M.F. (Blowin' Money Fast)" to two of Kanye's West's killer My Beautiful Dark Twisted Fantasy tracks, "Power" and "Runaway," made the top 10. But it was Usher's bombastic party jam "OMG" that rose to the top and came in at #1.

So what made that song such a party anthem? "Oh my God! That's exactly what I would say! Oh my God!" Pauly D joked about 2010's top party jam. "Dope, dope track. I love playing it. The crowd goes crazy when I play it. Usher's the man!"

Travie McCoy added: "It's a great song. It's undeniable, you know what I mean?"

"Dancing With the Stars" pro Lacey Schwimmer admitted that "OMG" was the track that got dancers, both professional and amateur, on the dance floor. "You guys got a great dance anthem," she said. "So be prepared for people who do not know how to dance just going to town!"

Producer Alex Da Kid gave props to will.i.am for the song's epic beat. "I love 'OMG.' I think it's definitely something different for Usher," he said. "And it still has all the dance performance elements Usher's known for, but it's something slightly different and done in a will.i.am kind of way, and it's different and that's why it connected to so many different people. It's a great song."

Celebrities also weighed in on their favorite jams of 2010, choosing everything from Katy Perry's "Teenage Dream" and Willow Smith's "Whip My Hair" to B.o.B and Hayley Williams' "Airplanes."
