Unreleased MJ Songs Worth $250M

Michael Jackson

Dozens of Michael Jackson songs never heard before by fans will be released in 10 new albums over the next seven years, starting in November, according to a source close to the transaction.

The albums are part of a deal with Jackson's estate that could bring in $250 million to the late pop star's trust, the source said Tuesday.

When Jackson died last summer, he left behind huge debts -- estimated at about $500 million -- but he also owned a valuable music catalogue and dozens of unreleased recordings.

Sony's Columbia Epic Records, Jackson's record label for three decades, will "create new projects for Michael Jackson featuring the never-before-released Jackson recordings," Sony said.

"The first project featuring unreleased music is expected for release in November 2010."

The Sony contract was negotiated by John Branca and John McClain, the two men Jackson named in his will to run his estate.

"By all objective criteria, this agreement with Sony Music demonstrates the lasting power of Michael's music by exceeding all previous industry benchmarks," Branca said in a written statement released Tuesday.

Los Angeles County Judge Mitchell Beckloff, who is overseeing the probate of Jackson's estate, has approved the contract, according to the estate source, who asked not to be identified because he was not authorized to speak about details.

Fans can also look forward to re-releases of Jackson's solo albums. Epic already struck gold when it released the 25th-anniversary edition of "Thriller," which rose to the top of the sales charts in 2008.
