makes sense :) it also points to the idea that artpop could mean anything in the sense that she's asking to look beyond simple wigs, make up and all that image jazz and all the fanfare that has come to be associated with lady gaga and focus on what she is trying to say, and not necessarily on what she is doing explicitly. and the beauty of it all is that you don't know necessarily what "lies behind the aura". it could be anything. it could mean anything.
Aura is clearly about herself and revealing who she is "behind the Burqa", behind the image she has fixated into our minds. She also makes it the first track on the album to introduce this idea.
