Ten days after its release, The Weeknd seems determined to make sure his new album “After Hours” is a gift that keeps giving: At the stroke of midnight ET, he added three previously unreleased songs to the album’s deluxe edition: “Nothing Compares,” “Missed You” and “Final Lullaby.” The three songs are all collaborations with his longtime sonic associate DaHeala; “Nothing Compares” also features contributions from producer Ricky Reed, who helmed much of Lizzo’s smash “Cuz I Love You.”
