Queen worked with David Bowie on the single “Under Pressure”. The first-time collaboration with another artist was spontaneous, as Bowie happened to drop by the studio while Queen were recording. Upon its release, the song was extremely successful, reaching number one in the UK and featuring at number 31 on VH1’s 100 Greatest Songs of the ’80s.
Later in 1981, Queen released their first compilation album, titled Greatest Hits, which showcased the group’s highlights from 1974–1981. It is the best-selling album in UK Chart history, and has spent 450 weeks in the UK Album Chart. The album is certified eight times platinum in the United States, and has sold over 25 million copies worldwide.
