It's the first collaboration between Outkast's Big Boi and Andre 3000 in years, with Frank Ocean, too.

Outkast's Andre 3000 tells Rolling Stone, I don't know the future of music right now. I have no idea what I do."

A great single was released, a great artist recorded his last song, important musicians were born, and other important non-Halloween October 31 milestones.

Big Boi from Outkast was arrested over the weekend when a drug-sniffing border patrol dog smelled something suspicious on him as he was getting off of a cruise ship in Miami.
