Swedish popular music, also called Swedish pop music, or just Swedish pop, refers to music that has swept the Swedish mainstream at any given point in recent times. After World War II, Swedish pop music was heavily influenced by American jazz, and then by rock-and-roll from the U.S. and the U.K. in the 1950s and 60s, before developing into the dansband music. Since the 1970s, Swedish pop music has come to international prominence with bands singing in English, ranking high on the British, New Zealand, American, and Australian charts and making Sweden one of the world's top exporter of popular music by gross domestic product.
