47. U2 - The Joshua Tree: Spawning U2's massive hit 'With Or Without You', their fifth studio album garnered much critical acclaim and has sold 25 million copies across the globe. It's influence, however, is arguably immeasurable.
46. Simon & Garfunkel - Bridge Over Troubled Water: The last album by folk rockers Simon & Garfunkel was their masterpiece. Released in 1970 it has since sold 25 million copies, but the pair split after it's release despite its critical and commercial success.

43. Mariah Carey - Daydream: The fifth studio album by the pop singer, and the first of her albums to appear on this list, Daydream was released in 1995 and had a more R&B influenced sound than anything Carey had put out before. The new twist proved popular, and it has since sold 25 million copies.
42. Madonna - True Blue: Madonna's 1986 album was dedicated to her then husband Sean Penn, and featured the single 'Papa Don't Preach'. Considered her most outwardly girlish record, it's her first album in this list, selling 25 million copies.

Originally released in 1984 it was put out again in 1985 to include her hit 'Into The Groove', which joined her other smashes 'Like A Virgin' and 'Material Girl'. It has now scored over 25 million copies sold.
Carole King - Tapestry: This second album by the singer-songwriter Carole King has not only sold 25 million copies in its lifetime, but also won the grammy for album of the year in 1972.

37. Britney Spears - ...Baby One More Time: Spears' debut features her biggest track and everyone's go to karaoke choice 'Hit Me Baby One More Time'. The song was originally intended for R&B group TLC but Spears claimed it after they rejected it, saying she knew it was going to be a hit. The strength of that single has helped shift 28 million copies since its 1999 release.
36. Grease: The Original Soundtrack From The Motion Picture: TELL ME MORE, TELL ME MORE. John Travolta and Olivia Newton-John's doo-wop fifties high school music film was a box office smash and the soundtrack followed in its footsteps, selling 28 million copies world wide.

33. Abba - Gold: Greatest Hits: The Swedish pop group captured the world's attention across their career, making their greatest hits compilation sales exceed the 28 million mark. The album enjoyed a surge in popularity after the 2008 film 'Mamma Mia' starring Meryl Streep became a box office hit.

It chronicles the life of character Pink, who struggles with abuse from school teachers, abandonment issues and the breakdown of his marriage until he seals himself off from society with a metaphorical wall - cheery stuff! It was inspired by Roger Waters frustration with the audiences on tour, where he'd imagine a wall between the crowd and himself.
29. Nirvana - Nevermind: Blowing the 'difficult second album' idea to shreds, Nirvana's 1991 LP was the first to feature Dave Grohl as drummer, and launched Nirvana into stardom with the success of single 'Smells Like Teen Spirt'.

Nine out of eleven tracks on the album were released as singles, including 'Bad', 'The Way You Make Me Feel', 'Man In The Mirror' and 'Smooth Criminal'. The album has sold between 30 and 45 million copies. We should also be grateful for the accompanying film, Moonwalker - in which MJ turns into both a car and a rabbit, which is wonderful.

24. James Horner - Titanic: Music From The Motion Picture: DiCaprio and Winslet's tragic romance may have made the film what it was, but the success of Celine Dion's trademark 'My Heart Will Go On' boosted this soundtrack to become one of the top selling records ever.

23. Whitney Houston - Whitney Houston: The debut album by Houston didn't immediately take off, but sales picked up in the summer of 1985 after its February release.

20. The Beatles - Abbey Road: 1969's eleventh studio album by the Beatles was the last album fully written by the band in session before they split, as 1970's Let It Be drew mostly from pre-written and recorded material. Lennon did not perform on four of the tracks and left the band when the album was released. A double A side single was put out - 'Something / Come Together' - and the album reached number 1 in the UK and the US. The album's iconic artwork has contributed to massive sales of over 30 million.

13. The Beatles - Sgt. Pepper's Lonely Hearts Club: The iconic artwork, featuring cameos from Edgar Allen Poe and Marilyn Monroe among others, has probably earned The Beatles eighth LP a few sales, which now total over 32 million.

11. Alanis Morissette - Jagged Little Pill: The album, with tracks like 'You Oughta Know' and 'Ironic', was released in 1995, and revolutionised the music world for female artists. The angst ridden stormy songs on the album were praised for their ability to soundtrack young adults' turbulent experience of romance worldwide. It was nominated for 9 grammy awards and won 5 of them, including best rock album and album of the year.
10. Led Zeppelin - Led Zeppelin IV: The album is actually untitled, but is commonly referred to as Led Zepplin IV. It was released in 1971 and featured no band name on the cover either, as the band wanted to remain 'anonymous'.

It's the most successful metal album ever and has sold a massive 37 million records since its release.
9. Shania Twain - Come On Over: Canadian singer Shania Twain came out with her third album in 1997.

Featuring the massive tracks 'That Don't Impress Me Much' as well as 'Man! I Feel Like A Woman' it has sold 39 million records since its release.
8. Fleetwood Mac - Rumours: Recorded to the backdrop of fraught relationships and crumbling marriages within the band, Rumours triumphed as the album of the year in 1977.

The album has sold over 40 million copies worldwide.
7. Bee Gees & Various Artists - Saturday Night Fever: The soundtrack to the 1977 film Saturday Night Fever shifted a huge 40 million copies. In the UK the album spent 18 weeks at number 1, with single 'Stayin' Alive' also hitting the top spot. The success of the album embodied the nation's obsession with disco.
6. AC/DC - Back In Black: Fittingly, the recording process of the rock band's seventh album was disrupted by the studio being hit by tropical storms. Additionally, the album's all black cover was designed a sign of mourning for their previous vocalist Bon Scott, who died before recording started. Featuring the singles 'You Shook Me All Night Long' and 'Hells Bells' it was a surprise hit, and has sold 40 million copies across the globe.
5. Eagles - Their Greatest Hits (1971-1975): Spanning only 4 years, the Eagles compilation record features 10 of their songs, all of which made the top 40 except from album track 'Desperado'. These included 'Take It Easy', 'One Of Those Nights' and 'Take It To The Limit'. It didn't even feature any tracks from Hotel California, as Greatest Hits was released in February and Hotel California was released in December of 1976. It has sold a massively successful 42 million copies.
4. Meat Loaf - Bat Out Of Hell: A collaboration with composer Jim Steinman, Bat Out Of Hell was developed by Steinman from Neverland, a sci-fi musical update of Peter Pan (bizarrely). They struggled to find anyone to sign them at first, and there are probably companies kicking themselves, as Bat Out Of Hell went on to sell 43 million copies and launched the massive singles 'You Took The Words Right Out Of My Mouth' and the title track 'Bat Out Of Hell'.
3. Whitney Houston & Various Artists - The Bodyguard: The best selling soundtrack ever, Whitney Houston featured on side 1 of the LP, with various other artists filling the second side.

2. Pink Floyd - The Dark Side Of The Moon: Progressive rock hit an all time high with Pink Floyd's eighth album. The recording process used some of the most advanced techniques of the time, including multitrack recording and tape loops. The iconic album sleeve was designed after keyboardist Richard Wright's requested a 'simple and bold' cover. Featuring 'Money', 'Us and Them' and 'Time' the album stayed in the charts for 741 weeks and boosted by its now legendary status, it has sold 45 million copies.
1. Michael Jackson - Thriller: Seven singles were released from Jackson's sixth LP, all of which hit the top 10 . 'Billie Jean', 'Wannabe Startin' Something', 'PYT (Pretty Young Thing)' 'Beat It' 'Human Nature' and 'Thriller' - the album is packed with hits and some of Jackson''s greatest songs. It was one of the first albums to use the music video as a means of promotion - with the video for Thriller becoming instantly recognisable after heavy rotation on MTV. The album cemented Jackson as a pop icon and has since sold between 51-65 million copies, dwarfing number 2 on this list's 45 million.
