Sales wise maybe but as far as quality albums, Kellz kept it consistent. Have you heard Love Letter, Write Me Back, or Black Panties? He could do a concert full of non-singles made throughout his career & rock it. Usher didn't perform not one song he made in the past decade at the halftime show, then dropped a turd of an album.
Usher did in fact perform songs he did in the last decade at the Halftime show. "OMG" and "There Goes My Baby" were last decade (2010-2019).
Those albums are not prime R. Kelly albums. And I've already stated R. Kelly>>>>. My point with bringing up R. Kelly is that his best music was clearly within the first 10 of his career. It was also his commercial peak. Same as Usher. Both have had hits since they peaked.
Did you just ask that?? It's only the biggest show in the world, why not promote your newer music?
