Shadorne, you are being a bit unfair , the Queen album is a greatest hits album whereas the others' are not, also why limit the sales to the UK ok, and not worldwide?, if so you would get a different picture, see below
I think these are approximates as I do not think anyone knows for sure;
The Beatles 1 billion,
Elvis 1 billion,
Thriller person 750m
Rolling and a Stones 600m
Abba 370m
zed dep 300m
Queen 300m
Flink ployd 210m
ac/dc 200m
U2 140m
The Who 100m
Dire straits 120m
Oasis 50m
I would rather hear Andrea Bocelli doing rock using only only 3 notes than dear old Freddie singing his 4 octaves!lol
The Queen track 'body language' ( on the greatest hits album), the worst song in the history of music, EVER!
(IMHO).
