The basis for the latest creditor's claim against Michael Jackson's estate -- and it could be a goldmine -- are the recordings Jackson made with Audio 4 Video Digital (A4V Digital, Inc.), says tmz.com.
The company filed a claim for US$736,502.59.
Sources say that Jackson had been recording songs shortly before he died and A4V was working on the music at the time of his death.
An A4V source says the company is a co-owner of the copyright for the sound recordings.
This could represent the last work of Michael Jackson so it could be very lucrative.
