An immense achievement, these are the absolute giants of modern music. The songs that need no introduction and that everybody can sing along to with somehow ingrained knowledge of the lyrics.
The top three then, will come as little surprise: Sir Elton John's 'Candle in the Wind '97'/'Something About The Way You Look Tonight' reigns at the top, followed by Band Aid and Queen's 'Bohemian Rhapsody' in second and third place respectively.
But dig a little deeper into the list of just 123 songs that have sold over 1 million copies since 1952, and you'll find some eyebrow-raising inclusions.
Alongside the pantheon of musical legends: The Beatles, Stevie Wonder, Abba, Oasis, Take That, New Order and Wham!, sit rogue singles from the likes of Aqua, Bob The Builder, Robson & Jerome and Shaggy - inspiring us to pull together our list of the '20 Worst Ever Million Selling Singles' in the UK.
True, these songs are often fun, memorable and - no doubt - catchier than the plague. And for that we salute them.
But for the million or so of you (us included) who bought them, have you listened to them recently? We thought not.
