Lady Gaga sprinkled some Willy Wonka-style dust on her Little Monsters on Thursday (May 28) with the surprise release of her Blackpink collab, "Sour Candy." The mouth-puckeringly sweet dance pop confection co-produced by BURNS and frequent collaborator BloodPop is a 2:38 bi-lingual bop that finds Gaga trading off verses with the South Korean girl group's members as they spin a tale of enticing love that requires some genuine, hard-to-crack effort.
