Apple has today announced that music downloads from its iTunes online music store have bypassed the 300 million mark.

Apple CEO Steve Jobs and Eddy Cue Apple’s vice-president of applications have both voiced their immense satisfaction at reaching the landmark achievement.

The iTunes music store now offers music lovers more than one million songs and is continually adding new tracks, such as this week’s addition of live recordings from the Grateful Dead and an exclusive version of Jack Johnson’s new album “In Between Dreams”.

Apple also confirmed today that the tsunami benefit single “Across the Universe” has become the most successful track in terms of first week sales.

The news of this latest iTunes success story suggest the iPod’s golden touch is still going strong, with consumers maintaining their interest and demand for related websites and iPod accessories.
