Madonna has a catalog filled with hit singles that the world seems to know every word to. It’s hard to pick which of her smashes might be her “biggest,” but now one track has emerged as her most successful, at least in the U.S.—and according to one metric.

“Vogue” has been certified three-times platinum by the RIAA. The Recording Industry Association of America has confirmed that the hit single has now moved at least three million equivalent units in the U.S. alone. That figure includes many actual purchases, as well as streaming equivalents.
