Whenever we need to liven the mood up, my friends and I will always throw on Guster's "Meow Mix" of "Keep it Together." Nothing gets you ready for a night on the town like hearing "Homecoming King" in nothing but cat noises.
In fact -- when we were tailgating for DMB in Indy, we tried to counter all the people playing Dave in the parking lot (concert rule violation #3) by playing a little Meow Mix.
