The studio is launching the bundle to coincide with the 30th anniversary of the artist's landmark solo albums Blizzard Of Ozz and Diary of a Madman.
Its track listing comprises 'Bark at the Moon', 'Diary of a Madman', 'Flying High Again', 'I Don't Know', 'Mama, I'm Coming Home', 'Mr. Crowley', 'Over the Mountain' and 'Steal Away (The Night)'.
'Mr. Crowley', 'Bark at the Moon' and 'Mama, I'm Coming Home' all include built-in Pro Guitar/Bass upgrades. The latter two are only available as part of the pack.
Rock Band 3 was released on multiple formats last November. Early this month, Harmonix pledged its support to the franchise despite the decline in the rhythm action genre.
The Ozzy Osbourne 8-pack is released for PS3, Wii and Xbox 360 on May 31 in the US, and on June 1 in Europe for $13.49 (£8.17).
