It's his time, his fame. I just don't understand what the appeal is but there again my parents never understood my tastes (if you can call them that) in 80's music. Likewise I never understood why girls went crazy over Donny Osmond, including when he was older, or The Beatles.
Will it last? Something tells me not. But this is their (younger generation's )time, not mine. Enjoy your fun while it lasts. Enjoy your money too Justin..invest it. And wear sun-block 😉
