MJ did say he was a fan of Ems older shit.

Em was kinda out of it when this happened so I wonder if he even knew about this. Em really should invest in buying the rights to his songs, he would make a lot more money if he was like MJ's estate and controlled the rights to MMLP and TES.
No wonder MJs estate was able to get out their some hundred million dollar debt so fast. Between the explosive sales Mike had in 2009/10, the Beatles remastering sales, and Ems comeback making kids buy the older albums they've got shit made.
