'Glee' will premiere its Season 3 kick-off episode, 'The Purple Piano Project,' on Sept. 20, and now that we've heard the list of songs prepped for the launch, we're more excited than ever!

When Ryan Murphy said he was taking it "back to basics" this time around, he wasn't kidding. The first episode of the season is packed with gleek-ed out versions of classic songs, as our favorite glee clubbers outline what they want to do when they grow up. One thing is for sure: They've got the beat, and you can't stop it.

We'll get a slew of musical numbers, like 'You Can't Stop the Beat' from 'Hairspray,' and a mash-up of 'Anything Goes' and 'Annie Get Your Gun' favorites, plus a Rachel/Kurt duet from everybody's favorite musical play (before it was a movie! gasp!), 'The Wizard of Oz.'

Additionally, New Directions will rock a pumped-up rendition of the Go-Go's 1980 smash hit, 'We Got the Beat,' and Blaine will perform Tom Jones' 'It's Not Unusual' solo.

Tune into FOX on Sept. 20 to catch the season premiere of 'Glee' -- 'The Purple Piano Project'! If you can't wait a few more days to catch 'Glee' fever, you can listen to the songs over on Facebook before the episode airs.
