"We nailed it: It's roller-skating! It's '90s! It's Ace of Base! It's Cyndi Lauper! It's like all these colors and more. There might be some really cool guest appearances by some cool rappers from the West Coast. I mean, you'll just have to see, since I'm a California girl, you know. And then some best friends might be appearing. … We'll see! It's going to be fun. It's going to be one of those records that is everybody's favorite guilty pleasure."
