I've never really understood, or rather jumped on, the Lana Del Rey backlash bandwagon. It's difficult for me to doubt her authenticity because she substantiates her presented persona in a way that's irreplaceable; I don't mean that we couldn't go on without her music, but that I couldn't imagine anyone else being her.
Maybe Tavi Gevinson understood the psychology of Del Rey best when she said, "[Lana] has many different qualities that women in our culture aren't allowed to be, all at once, so people are trying to find the inauthentic one." However, it's the multiple personalities that makes her enigmatic persona attractive, and by default then, her voice, which seems as organic an extension as possible.
"Young & Beautiful" comes from The Great Gatsby soundtrack and dilutes her friction to its purest, most alluring form. "Will you still love me when I'm no longer young and beautiful?" she haunts, "I know you will," with the supporting drama of an imagined full electronic orchestra.
If you're also as interested in hearing this soundtrack in full, as you are in seeing the movie, then check out a preview here.
