Adele's '21' named greatest album of all time

Los Angeles: Oscar-winning singer Adele's "21", that released in 2011, has been named the greatest album of all time by Billiboard.

The album topped magazine's Billboard 200 album list for its lengthy chart run, reported Entertainment Weekly.

"Adele's blockbuster 21 tops the Billboard 200's all-time albums ranking, fueled not only by the set's 24 nonconsecutive weeks atop the list (the most weeks at No 1 for an album by a woman), but also its lengthy chart run in the upper reaches of the tally," read a post on Billboard.

The second in the list was the soundtrack to "Sound of Music," while Michael Jackson's "Thriller" came third.

Having hits like "Rolling in the Deep" and "Set Fire to the Rain," the 27-year-old singer earned six Grammys, including Album of the Year for "21".
