André 3000, half of the hip-hop duo OutKast, celebrated his birthday, while his music continued to inspire covers by artists like Rivers Cuomo of Weezer, who performed unplugged renditions of OutKast tracks among others. OutKast was also honored with a Rock & Roll Hall of Fame induction, where André 3000 delivered an emotional speech, and the group's influence was further highlighted by T.I.'s son criticizing 50 Cent for sampling 'Ms. Jackson' without credit.
