Europop is a style of pop music characterized by polished production, simple and highly catchy melodies, repetitive choruses, and light lyrical themes. The style consolidated itself mainly in continental Europe from the mid to late 1960s, although it exerted significant influence on British and American artists, and topped the charts throughout the 1980s and 1990s, with revivals and moderate degrees of appreciation in the 2000s. The Swedish group ABBA is widely considered the leading representative of classic Europop.
