Kendrick Lamar and his “Not Like Us” Grammys

I don’t get how Kendrick Lamar won so many Grammys yesterday. He’s a good rapper, but four or five awards? That seems a bit much when other artists had a bigger impact last year. It’s not that he doesn’t deserve recognition, but did he really outshine everyone else? In my opinion he didn't. I know I'm about to get downvoted to hell, but that's just my opinion,he's not an exceptional singer.
