LOS ANGELES?Sony Music will put on sale a collection of 10 previously unreleased songs by the late pop star Michael Jackson in November, Rolling Stone magazine reported.

The magazine said the estate of the singer, who died in June 2009, had reached an agreement with the record company on the use of unreleased songs from Jackson's vault.

The report said Jackson is believed to have left hard drives filled with unheard music, much of it recorded during his 1980s peak.

Jackson's manager Frank DiLeo told Rolling Stone that he estimates that the King of Pop's vaults contain more than 100 completed and unreleased songs, including collaborations with artists Akon, Will.i.am and Ne-Yo.

"There are a couple of songs we recorded for the Bad album that we had to cut that are just sensational," DiLeo said.

Rolling Stone said the album of never-before-heard Jackson songs will be the first in a 10-project, seven-year deal the Jackson estate signed with Sony Music in March 2010, worth $250 million, which also includes reissues of Jackson's classic albums, greatest hits sets and a DVD collection.

The eccentric genius died aged 50 from a drug overdose at a rented Los Angeles mansion on June 25 last year.

Jackson's doctor Conrad Murray has been charged with involuntary manslaughter in connection with the case and is expected to stand trial next year. Murray denies the charges.
