BEST: Iggy Azalea has one less problem with Ariana Grande in tow.
"Fancy" is my favorite brassy summer jam, and Iggy Azalea attacked it at the Billboard Music Awards with her usual sense of irreverence and fun. And when Ariana Grande jumped in with that kickass sax on "Problem"? We found ourselves in the middle of a stellar mashup of two great songs in the Billboard top ten. Tell me the last time you saw a mashup that energized and effective.
