There are lyricists who didn't dumb down to chase a hit. The only MC's that don't truly understand how to make a song. MC's that aren't capable of doing that shouldn't be MC's in the first place. Rakim sacrificed nothing to create "Paid In Full", "Eric B Is President", or "Microphone Fiend". Classic lyrical rap records that you could actually dance to. Mos Def had "Ms. Fat Booty" and that changed nothing about his artistry. LL Cool J has a slew of commercial songs where he didn't have to change who he was artistically. Nas didn't dummy down to create "If I Ruled The World" and when he had GOAT producers at his disposal, the results were Illmatic. When he worked with super-producers, this resulted in a classic in It Was Written. People panned songs like "You Owe Me", but it was not only a hit for him, he can still perform this song to this day to great reception from the crowd.
Pusha T models himself after Biggie, but Biggie had mainstream joints where he didn't sacrifice what made him Biggie. Biggie dropped "One More Chance" remix and "Who Shot Ya" without blinking.
Pusha T underperformed across the board. No other artist with his acclaim and standing would ever get away with having Kanye and Pharrell at their disposal and someone saying they had a very successful career. It would be like Game's The Documentary flopping and people saying he had a very successful career. Breh, had an all-star lineup of producers, GOAT Hip Hop producers at that, was signed to Dre, had the G-Unit stamp. Documentary was massive. And if we're talking established artists, look at what Busta did with Big Bang. "Touch It" was huge.
