Sometimes you just gotta let loose and party like the guys in LMFAO. They just wanna have a good time! And if they win you can bet there will be some serious partying going on backstage...

FUN FACT: The single has gone to number one in Australia, Belgium, Brazil, Canada, Denmark, France, Germany, Ireland, New Zealand, Switzerland, the United Kingdom and the United States. Phew!

We love her songs and we love her style -- there's nothing about Lady Gaga that we don't love! "Born This Way" is just one of her many amazing tunes and we totally agree with the sentiment behind it. We're all beautiful in our own ways. Thanks, Gaga, for reminding us of that!

FUN FACT: Lady Gaga wrote "Born This Way" in only 10 minutes!

Another inspirational song, Katy Perry's "Firework" teaches us that we all have that spark inside us and we can all shine as bright as superstars like Katy! Whether we can all rock blue hair is another story...

FUN FACT: According to Katy, the lyrics, 'like the 4th of July,' were originally, 'like a firefly,' because the bright bugs reminded her of fireworks at night.

Taylor Swift knows romance. "I see sparks fly whenever you smile." Awww! The lyrics in "Sparks Fly" read like the most adorable poem ever. We hope she gets her love story on stage at the KCAs!

FUN FACT: Taylor wrote the song when she was only 16!
