37. Outkast, "Rosa Parks"
The song that made the world fall in love with Outkast brought earthy Southern flavor to the rap charts. Big Boi and André 3000's party rhymes were deceptively deep, and their flow was smoother than Georgia molasses. As for Rosa Parks: She felt the lyrics made light of her heroism and brought a lawsuit against the group. "We never intended the song to be about Rosa Parks," André told Rolling Stone at the time. "It was just symbolic, meaning that we were comin' back out, so all you other MCs move to the back of the bus."
