This was the internet is dangerous and needs to regulator, people just run of with comments to justify their on personal bias
Jay-Z never compared Beyonce to MJ or said she was bigger than MJ because she did coachella
He's merely pointing out the fact, When MJ was at the peak of his career Beyonce was 9 years old, Coachella wasn't even a thing back then, Beyonce has been famous since she was a teenager, and she's doing coachella which are kids far younger than her own age group and probably never heard of her destiny child albums, he's saying she's an evolution of MJ because of her longevity which has spanned generations, and he's right, MJ was popular with people's grandparents and their grand kids, he's career started in the 60s and peaked in the 90s, Beyonce is approaching nearly 30 years of revelance just like MJ
