First things first. When we say they shouldn't really exist we don't mean that we don't like the artists' music. In fact, many of them created some of our favourite hits of the '80s and '90s.
But we're not sure they really warrant a 'best of' album, given that these hits normally numbered in the single digits. And by 'single digits', we do of course mean one. Or occasionally two.
From 'The Best Of...' to 'The Very Best Of..', from 'The Collection' to the compilations named after their one hit (we're looking at you, 'The Power Of Love: The Best Of' Jennifer Rush), here are 20 dubious collections - and below, a playlist of hits so you can enjoy this trip down memory lane even more. Altogether now: "Am I living in a box/Am I living in a cardboard box..."
Living In A Box
Their hit: Living In A Box. Fun fact: The band never actually lived in a box. They lived in houses.
His hit: What Is Love. Fun fact: Despite his name, Haddaway was not, in fact, a Geordie.
Their hit: Last Night A DJ Saved My Life. Fun fact: The success of their 1982 hit led to compulsory first aid training for all DJs in New York City.
Her hit: The Power Of Love. Fun fact: The only thing bigger than Jennifer's hair were her shoulder pads.
Their hit: Funkytown. Fun fact: Sadly, like Avalon and Shangri-La, Funkytown doesn't actually exist.
His hit: Walking In Memphis. Fun fact: It is physically impossible to spend any time walking in Memphis without having this song in your head. (See also: winding your way down Baker Street.)
Their hits: The Lion Sleeps Tonight, Fantasy Island. Fun fact: Tight Fit have never actually been to a jungle, or a fantasy island.
His hit: Ice Ice Baby. Fun fact: Ice Ice Baby's real name is Robert Matthew Van Winkle but friends call him 'Rip'.
Their hit: Jump. Fun fact: Kris Kross named themselves after Kris Kristofferson.
Hue And Cry
Their hits: Labour Of Love, Looking For Linda. Fun fact: Labour Of Love was a protest song about the policies of Thatcher's government; Looking For Linda was about the band's love of Linda McCartney meals.
Their hits: The Harder I Try, Can You Keep A Secret. Fun fact: They weren't actually brothers.
Their hit: Groove Is In The Heart. Fun fact: Groove Is In The Heart is scientifically proven to get all people aged 35-45 onto any dance floor.
Ray Parker Jr.
His hit: Ghostbusters. Fun fact: When asked politely, any '80s child will do the 'Ghostbusters' walk for you.
Her hit: Rush Hour. Fun fact: Jane Wiedlin was rarely caught in a rush hour, due to her love of lying in and working late.
Their hit: Two Princes. Fun fact: The very fast line in this song is 'I know what a prince and lover ought to be'. Nobody in 1990 knew this.
His hits: Stop The Cavalry, You'll Always Find Me In The Kitchen At Parties Fun fact: By law, all British homes have to play 'Stop The Cavalry' at least once during the Christmas period.
Their hit: Pass The Dutchie. Fun fact: All '80s children were fooled into thinking a 'dutchie' was a type of bowl, when in fact it meant a joint.
His hit: The One And Only. Fun fact: Duncan Jones likes to include this song in every film he makes. His next movie is the biopic of Chesney Hawkes.
Their hit: More Than Words. Fun fact: At least 5.6 million schoolgirls harmonised along to this in their bedrooms in 1991.
His hit: Under The Boardwalk, Respect Yourself. Fun fact: Bruce Willis has never knowingly sung an original song.
