Lana Del Rey is one of the most transfixing pop artists to emerge in the past few years. Her music is lush, dark and intimate, and her voice exudes an air of mystery and immersion. "Once Upon a Dream," originally from Disney's classic Sleeping Beauty, is classic Lana, and is her fitting contribution to the upcoming Disney film, Maleficent. The film, starring Angelina Jolie, opens in theaters on May 30th. Get the track for free for a limited time, exclusively on Google Play.
