Every year since she blew up in 2008 with her album The Fame, Lady Gaga one-ups herself. Recently, we've been lucky enough to watch her roll around in cake for her new trap-rap song for her upcoming 2013 album ARTPOP.
Undoubtedly, Gaga has become our generation's glam icon for her style, music, and public advocacy. And whether she's decked out in a dress made of meat or belting it on while playing the piano, she's cemented her position as one of the most memorable musicians of all time.
