Tbh I don't see why so many of you are so upset over her losing. I saw it coming and wasn't at all shocked with the result. I still don't see what is so great about Adele. I've never cared for her voice.
On a flip note, who cares if Katy has never won? Critics and awards can not dictate how great an artist truly is. The music industry isn't 100% about the music, the fans are a huge part of that. The fans decide how great you are, now what a few judges think. KISS' only huge award win was a PCA for "Beth". They get "snubbed" every year for the "Rock" and Roll "Hall of Fame". Yet despite all that they are still considered (and rightfully so) one of the greatest rock bands of all time. (I placed the quotes around the RNR hall of fame like that on purpose).
Point blank, who cares if she wins or loses an award, she's still one of the greatest of all time.
