Maggie Lindemann adds another pop confection to her name with the unveiling of her new single, “Obsessed.” The 19-year-old siren struck gold with last year’s “Pretty Girl” after a Cheat Codes remix went viral and racked up a cool 300 million streams on Spotify. The song’s breakout success seems to have drawn the budding hitmaker away from her moodier early material in favor of something a little brighter. Her latest continues her trend toward more optimistic productions, but it does so with a twist.
