* BlackSheepHit: Most people who heard "Hey Ya!" don't even know [=OutKast=] are a rap group.
** This troper found that, upon playing ''Aquemeni'' to his cousin, that she (for one) was under the impression (thanks to the mass worldwide success of "Hey Ya!") that [=OutKast=] was one man (Andre 3000) who sung pop and jazz-influenced Motown songs. There was considerable surprise for her upon hearing "Return of the Gangsta", "Rosa Parks" etc.
* ExecutiveMeddling: After their previous label, [=LaFace=] was bought by Jive Records, [=OutKast=] had numerous clashes and creative differences, that ultimately led to Big Boi releasing his solo album with another label.
* HeyItsThatVoice: CeeLoGreen guests on many of their songs. This was before he became known as part of Gnarls Barkley or for his own solo work.
* NamesTheSame: Andre 3000 was originally known as just "Dre". He changed it to avoid confusion with Dr. Dre.
* WhatCouldHaveBeen: According to an interview with Big Boi, Outkast were asked to perform a UsefulNotes/SuperBowl halftime show, but turned it down: They wouldn't be given enough time to perform both "Hey Ya!" and "The Way You Move" in their entirety, and André 3000 refused to entertain the idea of shortening the songs or performing them as a medley. It was never specified which Super Bowl this was, but given the time frame when those songs were at their most popular, Super Bowl XXXVIII seems plausible: This would be significant because the halftime show that did occur that year is mainly remembered for being the TropeNamer for WardrobeMalfunction.
