Glee heads to New York City on Tuesday night, as the New Directions take on the country's best at Nationals.

But the competition won't be easy, considering the recently-released cover of Usher's "Yeah!" that has hit the Internet. Sang by an all-female group at the event, the members ask each other to "show me whatcha' workin' with" and order one another to "shake ya ass."

Take a listen now. Can Rachel and company compete?

Among other songs that will be featured on the finale:

• Bella Note (sang by New Directions)
• Still Got Tonight (Will Shuester)
• As Long As You're There (Sunshine Corazon)
• Pretending (Rachel & Finn)
• Light Up the World (New Directions)
