#303 ABBA, 'The Definitive Collection' (2001)

ABBA are one of the biggest groups of all time. Their sales are estimated between 150 million and 380 million records sold, 11.2 million singles sold in the UK alone plus 8 consecutive #1 albums, once again in the UK. They are simply one of the best-selling artists of all time. Their songs are ubiquitous. I had them playing in my head simply by reading the tracklisting.
