A bulk of 60 plus songs by Michael Jackson has been included in a record-breaking deal that will add up to 132.5 million pounds to the star’’s estate.

John Branca, who broke the deal along with co-executor John McClain and team of lawyers, revealed Sony Music Entertainment bought new Jackson music, some of which has never been released and was recorded with other artists in the last three years.

“Michael had a tendency to over-record. He would record 20, 30, 40 songs for one album. These are the vintage songs,” The Mirror quoted Branca as saying.

Branca added Jackson’s both old and new material may end up in some of the future albums.

Speaking about the Sony deal, Branca added: “The remarkable thing is to make the biggest deal in history in a market with declining record sales. It’’s a pretty big thing.”
