There’s no one like Mariah Carey. The singer from Long Island with the five-octave range has had 18 number-one singles (more than anyone but the Beatles!) and shows no sign of slowing down, with a new album due in May. She celebrates her birthday this week, and in appreciation of her amazing career, we’ve put together a station that counts down your favorite Mariah tracks of all time. We use what we call the Engagement Quotient, or “E.Q.,” which adds up plays, favorites, skips and bans to get a definitive countdown. It’s the Mariah Carey Top 33.
