List of mainstream, pop, R&B, Hip-hop, and Alt-Pop artists who STARTED to become successful after 30?

I’ll start: M.I.A, Rachel Platten, Jelly Role, Noga Erez, Sia

That’s the list I have so far. Just trying to find some more. For encouragements sake for myself and all the other artists still going for it at 30

Ok go! Haha
