Michael Jackson's estate is preparing to make a massive deal for half of his catalog. TMZ reports MJ's estate is considering selling a 50-percent interest for nearly nine-hundred-million-dollars. There appears to be talk of a sale happening between the estate and Sony, which was Jackson's long-term label. Reports say the sale would only go down if the estate maintains total control and management over the catalog. If actualized, it would be the biggest deal ever in the music catalog market.
