Lamar vs. Macklemore

In one of my sessions of Music Appreciation we got into a heated discussion about the Grammy Awards this year.  Each artist came to the awards with the same amount of nominations but Macklemore was the only one to walk away with any awards.  Some of my students had some strong ideas for and against this turn out.  What do you think? Who should have won and why?
