As expected, 'Glee' is slated to outdo itself in Season 3. The season premiere episode, 'The Purple Piano Project,' launches Sept. 20, and it will be packing great new tracks, like 'You Can't Stop the Beat' from the musical 'Hairspray,' for the ride.

Like a good teacher's pet, Rachel takes the lead to get New Directions going in this ditty. From the get-go, we're expecting a sappy, slow ballad, but by the :50 mark, when the star of the show declares that you just can't stop the beat, it's clear that we're in for a total fun fest with this track. Thank goodness.

Once the beat picks up and the chorus starts, we take a deep breath and realize that the 'Hairspray' tune will showcase all of our favorite stars and is upbeat, peppy and fun -- just what 'Glee' needs to make its entrance into the fall television lineup.

"'Cause you cant stop / The motion of the ocean / Or the sun in the sky / You can wonder if you wanna / But I never ask why," the glee club sings in unison as they gain momentum with the chorus. 'You Can't Stop the Beat' is unstoppable from that point on, much like the hit FOX show.

With lines from Kurt, Artie, Mercedes and more, and elements of those classic swing dance tunes that we all deny loving, we think this was the perfect song for the show's re-entry. The Purple Piano Project' airs Tuesday, Sept. 20 in its regular 8PM ET time slot -- always on FOX.
