Creating the perfect album is an art form. It is a skill that requires careful planning and skillful assembling of songs. The results are a musical masterpiece that will hold a special place in the hearts of music fans for years to come.

In order to compile the list of best selling albums, Mental Floss consulted the data of the Record Industry Association of America (RIAA). The RIAA measures certified units sold. This includes physical copies as well as digital downloads.

Among the albums that have sold over a million copies in a single week are The Beatles’ 1967 – 1970, Led Zeppelin’s The Song Remains the Same, Harry Belafonte’s Calypso, and Eminem’s Marshall Mathers LP. There are also three albums by Pink Floyd, including Dark Side of the Moon, and one by Fleetwood Mac, Rumours.

One of the most popular album covers in the world is that of The Dark Side of the Moon. The album was inspired by the deteriorating health of Syd Barrett.

The album stayed on the US charts for 900 weeks, becoming one of the top selling albums of all time. In addition to the iconic cover, the album also explored time, greed, and death. It sold over 46 million copies worldwide.

It is a testament to the longevity of the music that Eagles have been able to maintain two albums in the top three best selling albums of all time. Their greatest hits 1971-1975 have now been certified 38x Platinum.
