First off, this nikka Tank ain't slick with sliding himself as being of similar talent and importance as Michael Jackson, Chris Brown, and Usher.
But, his argument makes sense depending on how old you are. You gotta remember that for a LOT of people, Michael Jackson is effectively nothing more than a legend that people who are currently middle aged and older tell them about. The height of his career was in the 80s. Thats 40 years ago, brehs. And while his career continued into the 90s and 2000s, the allegations against him and general weirdness around him definitely make the latter period a bit muted. Additionally, for some people, Michael Jackson's legacy is complicated, and celebrating his catalog is a bit of a challenge.
For a lot of the people having this argument, Chris Brown is far more present as being part of their lives, and for better or worse, the fukkery around Chris Brown is easier for them to overlook than Michael Jackson's. So, for people like that, I can see how they could come to the conclusion that Chris Brown is better. I disagree, but I understand.
Tank is 48. He knows, he just loves kissing up to Chris Brown and being a hot take whore for the shaderoom crowd
