Upon its release , " Think Twice " became a hit in Europe and Australia . Uniquely for Dion 's discography , whilst the song was not a major hit in America , it was a runaway hit in the United Kingdom , going on to be one of the biggest-selling records of all time . It remains Dion 's second-biggest hit in the UK , eclipsed only by " My Heart Will Go On , " and is widely credited amongst British fans as cementing Dion , previously most-known in the United Kingdom for her victory in the 1988 Eurovision Song Contest , as a major star to British audiences
