Andre 3000 has been making surprise appearances throughout the summer. Apart from production credits on Big Boi's 'Sir Lucious Left Foot: The Son of Chico Dusty' and the leaked collaboration 'Lookin for Ya' with Sleepy Brown, the other half of Outkast has dropped the new sentimental track 'I Do.' The snippet samples Lenny Williams' 'Cause I Love You' and is apparently off of the 'Limelight Exclusives' mixtape hitting the streets tomorrow, Aug. 12. A full-length version of the track, with a Young Jeezy feature, is rumored for Jeezy's forthcoming 'TM 103.'
