There's some controversy behind the song because some are calling it an Outkast feature but Andre publically stated it wasn't..I don't follow Andre too closely but it sounds like Andre always avoids Big Boi or some shit. He's being a little bitch about getting back together imo
Either way, Big Boi's verse is dope
