40. George Michael - 'Careless Whisper': Oh George, what happened? Before a seemingly endless string of controversial incidents, (It's one person per cubicle, Mr Michael) the ex Wham star's debut solo single sold 1.46 million copies in the UK and reached number 1 status in a whopping 25 countries.

38. Coolio featuring LV - 'Gangsters Paradise': A rare and welcome moment of hip hop in this chart, with the now forgotten Coolio sampling Stevie Wonder's"Pastime Paradise in a song concerning the pitfalls of gang culture. It sold 1.47 million copies in the UK.

37. Gotye featuring Kimbra - 'Somebody That I Used To Know': It was so overplayed you couldn't help but recite the chorus endlessly like a shaman performing a bizarre ritual on a mountain top. It transfixed the British public and sold 1.48 million copies.

36. Culture Club - 'Karma Chameleon': Before Boy George descended into a pit of controversy and trouble, his group Culture Club released a disco pumping track about alienation, with the single selling 1.49 million copies.

35. Maroon 5 featuring Christiana Agulera - 'Moves Like Jagger': Once an inoffensive pop band attempting to embrace their inner Jamoroquis, this unacceptably catchy song sold 1.49 million copies and marked their permanent entry into a sea of syrupy sweet, cardboard cut outs.

34. Ken Dodd - 'Tears': First recored by Rudy Vallee in 1929, comedian Ken Dodd allowed this sweet and frank lullaby to be adored by the masses. The single moved 1.52 million copies.

33. Survivor - 'Eye of the Tiger': No complaints here. Play Survivor's fist pumping and motivational Rocky anthem when you're at your lowest for a swift punch of, 'Come on!' The track shifted 1.53 million copies.

32. Britney Spears - 'Baby One More Time': This song took over the world (and so did Britney) when it stormed radios and television screens across the globe, selling 1.54 copies in the UK alone. The video arguably defined the aesthetic of a whole MTV generation.

31. The Beatles - 'Can't Buy Me Love': Unsurprisingly, not the only appearance John Lennon and the boys will make on this list. The track sold 1.54 million copies and was composed by Paul McCartney in the 5 star Paris Hotel, George V.

30. Baddiel & Skinner and the Lightning Seeds - 'Three Lions: Made famous by Daniel Baddiel and Frank Skinner, it was the official anthem for England's 1996 Euro's and roused enough national pride to sell 1.54 million copies.

29. Celine Dion - 'My Heart Will Go On': Made famous by the endlessly parodied "I feel like I'm flying' sequence in the monster James Cameron Hit, Titanic. it sold 1.55 million copies in the UK, melting the hearts of millions. Does it really belong on the list though?

28. Various Artists - 'Perfect Day': It should be the original version famously featured in Trainspotting, but it's still a piercingly poignant record which many have interpreted as Lou Reed's dark love letter to heroin. It sold 1.55 million copies in the UK. Try getting the refrain of 'REEP REEP REEP' out of your head, as well - or Huey Morgan's 'JEAH'.

27. Adele - 'Someone Like You': Taken from Adele's record breaking album, 21, this single alone sold 1.57 million copies in the UK. It%u2019s hard to argue with the phenomenal combination of both songwriting and vocals, as well as the welcome surge it brought back to physical copy sales.

26. Whitney Houston - 'I Will Always Love You': Kevin Costner brought the Dolly Parton song to Houston on the set of The Bodyguard as a soundtrack suggestion. It's a monster of a power ballad which sold 1.58 million copies in the UK alone.

25. Human League - 'Don%u2019t You Want Me': Don't you want me baby? Seriously..don't you? Selling 1.58 million copies in the UK, it defined the bubbly razzmatazz and roller-skates of the huge hair 80's. A stone cold classic and one of the best pop songs of all time.

24. Frankie Goes To Hollywood -'Two Tribes': A bizarre entry which confirms the true kookiness of the British public. Selling 1.59 million copies, the song combines thumping bass with snippets of public service announcements about nuclear attack procedures. Madness.

23. Puff Daddy featuring Faith Evans - 'Missing You': Ah, when puffy was just puffy before the endless sequence of pointless name changes (Swag, really?). A solid hip hop anthem and an ode to Biggy Smalls from his best friend and wife after his untimely death. It sold 1.59 million copies.

22. John Travolta and Olivia Newton John - 'Summer Nights': Oh Lordy. It's the obligatory wedding song that fills all with a combined sense of dread and guilty pleasure. It sold 1.6 million copies in the UK, and If you like musicals, then you love Grease.

21. Robin Thicke featuring T.I and Pharrell Williams - 'Blurred Lines': Remember that song with a bunch of beautiful naked women dancing aimlessly around a group of smug multi-millionaires? Unfortunately, so do we and at least 1.63 million others. I guess we can take solace in the fact that Robin Thicke's album immediately plummeted into the deep, dark depths of absolutely nowhere. The track and video were also banned in numberous universities and clubs after being accused of promoting rape.

20. John Lennon - 'Imagine': This was John Lennon's most successful solo outing by far. We can't argue with the sheer optimism and beauty of this song, and it definitely deserved to sell 1.64 million copies in the UK alone.

19. Wham - 'Last Christmas': Back when the Christmas number one wasn't being hijacked annually by reality drivel, Wham stormed the charts with a painfully over-sentimental but difficult to hate love song. It sold a whopping 1.7 million copies. Check out some pretty brilliant covers of the track by the likes of Manic Street Preachers and Jimmy Eat World too.

18. Bryan Adams - '(Everything I do) I Do It For You': Combine the song with the post-modern Robin Hood themed video and you have the cheese of all cheeses. People went crackers for it (sorry) and It sold 1.75 million copies.

17. Cher - 'Believe': And the cheese just keeps coming. For all those who may be currently suffering from a heart break, we at Gigwise do in fact believe in life after love. Cher%u2019s trancy power ballad sold 1.79 million copies. It's also one of the tracks that inspired Kanye West's heavy use of autotune. Make of that what you will...

16. Will Young - 'Evergreen': This Westlife cover sold 1.79 million copies in the UK, doing more business than Lennon's 'Imagine.' This is beyond insane, but it's pretty difficult to get mad at a man who is so nice that he probably runs his own abandoned puppy/kitten sanctuary.

15. The Beatles - 'I Want To Hold Your Hand': In a strange series of events, this single had to contend with the band's previous single, 'She loves you', for the No.1 spot. It sold over 1 million copies in advanced orders and went on to sell another 790,000.

14. Aqua - 'Barbie Girl': This one is probably the hardest to stomach so far. The super syrupy barbie doll anthem sold 1.8 million copies and the less that's said about that, the better.

13. Pharrell Williams - 'Happy': Clap along if you feel like this was probably the most overplayed pop song on the radio in the history of mankind. The N.E.R.D founder has been letting kids up on stage to boogie with him recently though, and that's pretty cute. The record sold 1.81 million copies.

12. Stevie Wonder - 'I Just Called To Say I Love You': If Mr. Wonder didn't make an appearance on this list, we'd be pretty heartbroken. It sold 1.84 million copies and to this day still serves as Motown Records biggest selling single in the UK.

11. The Righteous Brothers - 'Unchained Melody': The song was composed for a widely unknown prison film called Unchained, but has spawned an estimated 500 interpretations in hundreds of different languages. The Righteous Brothers version alone sold over 1.86 million copies.

9. We Wet Wet - 'Love Is All Around': I feel it in my fingers, I feel it in my...nose? Wait a minute. Wet Wet Wet's cover of a previous Troggs song sold 1.86 million copies after Four Weddings and a Funeral's phenomenal success, proving how sentimental all of us in the UK are.

8. The Beatles - 'She Loves You': Lennon and Paul McCartney composed and completed this undeniably catchy classic in under 2 days, proving he pair's talents for both songwriting and seamless collaboration. It's no wonder the record made its way to 1.91 million members of the British public.

7. Boney M - 'Rivers of Babylon': Boney M had a heck of a year in 1978 with two gigantic hits, obliterating the charts by selling just over 2 million copies with this soulful cover of The Melodians%u2019s Rastafari record.

6. Frankie Goes To Hollywood - 'Relax': Selling 2.03 million copies in 1984, it also featured on the Grand Theft Auto: Vice City soundtrack. Many twenty somethings will remember committing unforgivable acts on pedestrians while riding along to this infectious disco number. The track and video were banned on radio and television for quite some time for it's promotion of the homosexual lifestyle, when the world was gripped by the fear of HIV.

5. John Travolta and Olivia Newton-John- 'You're The One That I Want': The gargantuan success of Grease allowed this romantic, jivey number to sell 2.05 million copies in the UK. Just don't count on Travolta to solve the ongoing Euro-crisis.

4. Wings - 'Mull of Kintyre': This one is a little baffling. A melodic ode to the Kintyre peninsula in Scotland, the song breezes along before slapping you in the head with an army of truly unnecessary bagpipes. Alas, it sold 2.08 million copies.

3. Queen - 'Bohemian Rhapsody': Freddie Mercury's mesmerising mix of ballad, opera and hard rock is one that shook stadiums to the core when the band were at their peak. A zany British public purchased 2.44 million copies of the anthem.

2. Band Aid - 'Do they know it's Christmas?': The first and most powerful supergroup formed by Bob Geldof and Midge Ure, with the record selling a staggering 3.75 million copies. The huge sums raised for various third world crises are simply undeniable.

1. Elton John - 'Candle in the Wind': Did you guess right? Sir Elton Hercules John (we're not kidding) re-recorded this previous hit in honour of princess Diana's death. Selling an unbelievable 4.92 million copies in the UK, it emphasised not only the song writing talents of the musician, but the public fascination with this particular member of the royal family.
