Recorded with the intention of making "a pop album", the album's music featured a pop rock and soft rock sound characterized by accented rhythms and electric keyboards such as the Fender Rhodes or Hammond B3 organ. The members partied and used cocaine for much of the recording sessions, and its completion was delayed by its mixing process, but was finished by the end of 1976. Following the album's release, Fleetwood Mac undertook worldwide promotional tours. Rumours became the band's first number one album on the UK Albums Chart and also topped the US Billboard 200. The songs "Go Your Own Way", "Dreams", "Don't Stop", and "You Make Loving Fun" were released as singles, all of which reached the US top 10.
Featuring a soft rock and pop rock sound, Rumours is built around a mix of acoustic and electric instrumentation. Buckingham's guitar work and Christine McVie's use of Fender Rhodes piano or Hammond B-3 organ are present on all but two tracks. The record often includes stressed drum sounds and distinctive percussion such as congas and maracas.
