As they got on the vehicle, which was surrounded by a large group of fans who decided to stick around to catch a glimpse of the band, they heard one of the local radio stations announce that they were going to premiere Paramore's song "Misery Business" right then and there. "We opened up all the windows and let all the fans listen to it," Williams told Radio.com, "and we just partied."

The frontwoman says it was "a cool feeling" to hear her song on the radio and even now when she catches one of her songs on the radio, she gets excited. "Every time I hear it, I blast it out like I'm the biggest Paramore fan in the world," Williams said.

Since the very beginning, Williams and her fans have had a special bond. And she says the fans have played a big role in her band's success. "Honestly, we have the coolest fans, she said. "They're some of the smartest fans and they're working for us really."

It's true, Paramore fans have put in time making sure their favorite band continues to be played on radio even now, six years after Williams rolled down those tour bus windows. They call in to local stations requesting Paramore songs and now, with Facebook and Twitter, they've come up with more technologically advanced ways to get the band's songs played over the airwaves.
