Rumours is Fleetwood Mac's most successful release; along with winning the Grammy Album Of The Year 1978 the record has sold over 45 million copies worldwide, making it one of the best selling albums of all time. Rumours has received diamond certifications in several countries, including the US, Canada and Australia.The band wanted to expand on the commercial success of the 1975 record Fleetwood Mac but struggled with relationship breakups before recording started. The Rumours studio sessions were marked by hedonistic behaviour and interpersonal strife between Fleetwood Mac members; these experiences shaped the album's lyrics.
