Things are coming together nicely on the set of "ABDC." All the crews have been practicing their routines multiple times a day in order to get it right. One thing's for sure: You can expect this Thursday night to be a dance-packed finale! Here is what everyone will be struttin' their stuff to:

West: Ke$ha "Blah Blah Blah"
South: T-Pain "Take Your Shirt Off"
East: Cobra Starship "Hot Mess"

While the Top 2's performance song is a surprise, we can tell you that the winning crew will close out the show to Kevin Rudolf's "I Made It."

Blueprint Cru and Poreotix are steppin' out of their respective boxes this week for a joint performance -- and producers got Strikers All-Stars' lead man, Tallie Brinson, to show them how to step correctly.

Although Tallie won't actually perform on Thursday night, he's excited to return to the show. "Being back on the stage brings back a lot of good memories," he told us. "I'm remembering the jitters and butterflies in my stomach, and the pressure to do good ... It's just a mixture of powerful emotions."

"I think it's great that MTV and "ABDC" are pushing these crews outside their boxes because that's what this competition is all about -- pushing your limits."

Everyone here on the "ABDC" set has been working overtime trying to perfect their regional group performances. Especially the East Coast crews, who decided to incorporate a jumping section into their routine, à la Saltare. And who better to teach them than the rope-masters themselves?

"I teach kids all the time how to jump, and [the other dancers] have learned in a day what it takes most people a month to pick up," Saltare's Tyler Perez told us in rehearsals on Saturday.

Hopefully, they'll have all their jumpin' moves down pat come this Thursday 10/9c. Make sure you tune into the Live Finale to see how it all unfolds!
