Katy not having a grammy is not a surprise, it's not like her music is acclaimed by critics or that she actually make good music but they still snubbed her.
She's the least acclaimed major pop girl of all time (lowest selling major pop girl too)
They would matter even less, actually. At least now they are putting up the facade of being discerning. It's like if the Oscars decided to nominate Jurassic World.
The argument of "look they won a grammy now they are over" is kinda pointless I bet many have won the Academy Award and flipped to oblivion, it dosen't make it less prestigious.
I want Katy and Britney to win televised Grammys just to see the reactions of the people who say Grammys don't matter. Like you know there will be tears of joy and backflips.
