She did submitted NF in the category Pop Vocal Female.
I love NF and I would have the happiest day in my life if NF got nominated in that category, but truth is, the song isn't qualyfied enough. I'd love to see ATM, OD and WH got nominated, but NF.., no way. Still, I don't know why they didn't submitted the song in "Song of the year" and "record of the year". It would have higher hopes in these categories.
I still couldn't believe some of the nominations Norah Jones, U2, Dixie chicks, Sheryl Crow... got, I know they are legend, but some are just not fair
