An article by Ed Christman of Reuters.com is reporting that the albums will still be available on CD as EMI will still have stock that it can sell off, but will not be able to manufacture more copies until a new contract is signed. Other albums no longer available as a download include “The Final Cut” and Wish You Were Here”.

The bands earlier albums through to the “Dark Side of The Moon” are still available to download. Pink Floyd’s management started touting the bands entire music catalog for a new licensing deal around eighteen months ago. But some major record labels have found the bidding for the license too high.

Some label sources do not think Pink Floyd’s asking price will rocket, but the band has sold 36.2 million albums since 1991 in the US alone. This year so far 587,000 digital albums have been sold, and in the last two months of EMI’s deal “The Wall” sold 14,000 units.
