It's pretty cool for an artist to be nominated for a grammy. I don't know anything about this artist other than recognizing her name, but it's legit to list those nominations in your credentials. It's a real accomplishment.
In that case, the grammies are just a private back-patting club, nominations and winners are meaningless anyway and Minaj is a talentless lip syncing influencer. All of which is maybe a little bit true!
