On February 7 1987, Open Your Heart hit number-one on the Billboard Hot 100 in the U.S. The track was the 4th international single release from the True Blue album.

While the song has kept a relatively high-profile amongst Madonna’s hits through the years – having been included on the set-lists of four of her world tours (including her most recent MDNA Tour) and two of her greatest hits albums – the single attained only moderate success on the charts (by Madonna’s own standards) in most countries outside the U.S.

Open Your Heart peaked at number-eight in Canada; at number-six in Australia, Italy, Belgium and The Netherlands; and landed outside the top-ten in France (twenty-four), Switzerland (eleven), Germany (seventeen) and Austria (eighteen). It fared better in the UK, hitting number-four – and it achieved its highest European placement in Ireland, topping out at number-two.
