I think either Adele, Beyoncé or Rihanna deserved it.
Be realistic. Adele is too busy and Beyonce would never turn up to accept it. They awarded Gaga last year and Madonna this year, how is Ari any worse than them? She put out quality music to success with some great performances this year.
Ohhh I just realized it's probably cross-promo for the RH Tour film just like how her 2013 BBMA award was the promo for the MDNA film. Messy. But get it mama.
Who do you think should be the woman of the year, considering this award is not just about chart success or success in general, but other things too, which are mentioned in the OP ?
What is "mentioned in the OP" doesn't explain why she's getting it in 2016.
