i don't think Chris Brown has been A-list mainstream relevant since the thing with Rihanna. Where he is now, putting out music for his core fans and being in that dancer bag, he can keep going for a while.
He's not selling albums like 5, 10 yrs ago
His last joint is it platinum?
I would say he is always going to be able to eat touring
This 100%.If you can perform on stage you will always remain relevant. Add to the fact that there aren't other dancing/singing musicians on his level since 05, then you get your answer.
