Grammy performances 2015 ranged from brilliant to boring to just plain bad. At the Grammys this year, Annie Lennox, Beyonce, Sam Smith, Sia, Katy Perry and Ed Sheeran are being talked about the most for killing it with great live performances. Kanye West, Usher, Madonna and Lady Gaga, however, divided viewers with their controversial Grammy acts -- people either loved them or hated them. But what do you think? What was your favorite Grammy performance? Ariana Grande? AC/DC? Gwen Stefani? Miranda Lambert? Beck? Who was the worst Grammy performer of the night? Go ahead, vote on the Grammy performances you liked the best, or feel free to re-rank this list. Once can argue that the live performances at the 2014 Grammys were much stronger than those at the 2015 Grammys, but nonetheless, it's good fun to rank the best Grammy songs every year!
