Judas - Lady Gaga

Speed: 131 bpm

The DJ's Take: Apparently this song's getting a lot of buzz, but it sounds like your average Lady Gaga track to me - loud, heavy, and unapologetic. I do like it better than Born This Way. In any case, while it's still hot, add this to the greatest in-key mix ever made (on Beat Match City):

Turn on key adjust and mix with: Give Me Everything - Pitbull ft. Ne-Yo & Afrojack, Till The World Ends - Britney Spears, Tonight (I'm Lovin You) - Enrique Iglesias, Just Can't Get Enough - Black Eyed Peas, Hold It Against Me - Britney Spears, Beautiful - Akon, Break Your Heart - Taio Cruz, Cooler Than Me - Mike Posner, The Way You Move - Outkast, Pump Up The Jam - Technotronic, Sweet Dreams - Eurythmics, Baby Got Back - Sir Mix A Lot

Beautiful People - Chris Brown & Benny Benassi

Speed: 128 bpm

The DJ's Take: Somehow I feel like this is too light & European for American consumption. But I do give it an 8 out of 10 on the fist-pumpability scale, although you probably need to make it a little daintier than what they do on the Jersey Shore. Lots of buildup, which isn't a bad thing if your crowd needs a breather.

EDIT: Should've occurred to me earlier, but you should turn on key adjust and mix this with LMFAO's Party Rock. Someone's bound to be feeling that, right?

On The Floor - Jennifer Lopez ft. Pitbull

Speed: 130 bpm

The DJ's Take: Somehow I feel like they were going for that Euro/Mediterranean/foreign feel with this track, and they pull it off (at least to my inexperienced ears). I actually heard this for the first time last weekend, when we were in a party limo on the way to a club in Vegas. And it struck me that the recent dance music trend on the charts is perfect for someone like J. Lo, who can't sing. Get a good beat, doctor her voice to the point of presentability, and you've got a hit. Brilliant!

Turn on key adjust and mix with: S&M - Rihanna, Bulletproof - La Roux, Low - Flo Rida ft. T-Pain, Calabria - Enur

Party Rock Anthem - LMFAO

Speed: 130 bpm

The DJ's Take: I may be getting old & cynical, but I could still picture myself getting down to this at a party with a random female. It's basically just a ball of electric energy, and it can make a night of spinning top 40 a little more bearable. LMFAO seems like one of those groups that everybody knows and enjoys, even though they never really get to the top of the charts with any of their singles.

Turn on key adjust and mix with: Firework - Katy Perry, I Like It - Enrique Iglesias
