"Under Pressure", Queen's collaboration with David Bowie, was released in 1981 and became the band's second number one hit in the UK. Although included on "Hot Space", the song was a separate project and was recorded ahead of the album, before the controversy over Queen's new disco-influenced rock sound. The album's second single, "Body Language", peaked at number 11 on the US charts, and estimated sales of the album stand at 3.5 million copies. In July 2004, "Q" magazine listed "Hot Space" as one of the top fifteen albums "where great rock acts lost the plot".
