The prime minister has picked Pink Floyd's seminal 1973 album Dark Side of the Moon as his favourite record of all time.
The choice, which was announced on his Facebook page, was made as part of the celebration of Great British Music.
It does not quite match up to his previous statements on the subject, when he said The Smiths' The Queen Is Dead was his favourite album.
The change of heart may have been inspired by guitarist Johnny Marr's promise that the group would get back together if the coalition was thrown out of office - or the fact that the Diamond Jubilee is now just weeks away.
Mr Cameron has also previously expressed his admiration for indie bands such as The Killers, Radiohead, Pulp and Blur.
The Pink Floyd album continues to win acclaim for its technical and artistic innovation, particularly on tracks like Money, which has an almost unheard of time signature of 7/4, Us And Them and On The Run.
Mr Cameron recently told the Sunday Telegraph his current choice of bands were Band of Horses and Lana Del Ray, but that his children's "appalling" pop music, such as Katy Perry, was starting to find its way on to his iPod.
