David Bowie's new single has been banned from the UK charts.

The legendary singer released "Where Are We Now?" - his first track in 10 years - on Tuesday to coincide with his 66th birthday and it shot straight to the top of the iTunes downloads chart. But as well as being sold, it is also being given away to fans who pre-order his album, so chart bosses say it cannot be counted.

The Official Charts Company said, "It is not possible to distinguish album sales from track sales from the retail data."

Bowie's album, The Next Day, is out in March but already tops the iTunes chart with advance orders.

Yesterday, it was revealed Bowie wanted his new album cover to be as "minimal and undesigned as possible." The main picture on The Next Day was made by the singer with design company Barnbrook, and features the cover of his 1977 album Heroes in black and white, with the middle part obscured by a white block featuring the album's title.

Writing on their blog, Barnbrook said, "We wanted the cover to be as minimal and undesigned as possible, we felt the most elegant solution was to use the original one from 'Heroes' and simply cross out the title of the old album. It has the detachment appropriate for the atmosphere of the new album."
