Apple sells sounds of silence on iTunes

Apple have started selling a number of silent 'music' tracks ... for 79p each.

Despite not being able to hear anything users will have to pay to download the tracks from the iTunes store before putting them on their iPod and not listening to them.

One of the silent tracks is John Lennon's "Nutopian International Anthem" which first appeared on his 1973 Mind Games album.

Because iTunes charges for individual tracks this means the six second long song can be bought individually and works out to about 13 pence per second of quiet, an impressive way of cashing in on nothing, even for Apple.
