AC/DC have finally released their entire catalog of music on Apple music store iTunes.

The band had previously voiced strong opposition to the digital service. Until now its members maintained their songs should not be made available for individual download because they were all integral parts of various albums.

But the Australian band's 16 studio records, four live albums and three compilations, which have sold more than 150 million physical copies worldwide, are now available in the iTunes store. All tracks are Mastered for iTunes, and fans have the ability to download full albums or simply purchase their favorite individual songs.

AC/DC's music videos were already viewed about 600,000 times a week online, according to their record label, Columbia Records.

The band has just released their first live records in 20 years, Live at River Plate, and have a 40th anniversary tour planned for 2013.

The Beatles back catalog was released for download in 2010 after years of disputes between rights holders. Some musicians are taking legal action against their record labels over the royalties they earn from download sales. James Taylor, Eminem and Sister Sledge are among those who have filed complaints.
