Nearly 15 years ago, Mariah Carey took aim at an extensively gossipy person spreading her business around. On “Obsessed,” the first single from Memoirs of an Imperfect Angel, opens with the songstress chuckling before asking: “Why are you so obsessed with me?” It’s the same question Ariana Grande tried to get to the bottom of on her latest single, “Yes, And,” where she ponders: “Why do you care so much whose — I ride? Why?” Naturally, Grande sought out Carey — an expert on dodging obsessed spectators — for the song’s official remix.
