This is the real reason why people demand he raps and like I said it's not from his fans and isn't about him personally. Outkast fans know he's not putting out a rap album. They're not expecting reunion.
Most of the people telling him to pick the mic back up are doing it because they don't think he deserves to be rated highly. They either didn't like Kast at all or liked Big Boi more. He should rap to prove to them that he's top 5 or 10 on someone's imaginary lists. Rap to justify Eminem's opinion. Rap to justify being rated over Big Boi.
Like I said earlier most of these people didn't like him anyway so why do they want him to rap? It's not because they want to hear it. He puts out an album they're just going to pick it apart (probably without listening) and say he's not worthy of making a list.
Stop pretending like you care. He's been out of the spotlight for 2 decades but does 4 interviews and he's an attention whore. He doesn't post on social media. He's real easy to ignore. Getting triggered over someone not releasing music you never wanted to hear is crazy.
Saying this generation no longer cares means nothing. Every legacy act goes through that. Nas last album sold 16k first week. If Dre announced a rap album it would sell more than that. His flute album did 24k first week
