DJ Premier unreleased beats for Jay and Rakim?

[DEEJAY*]

Does anyone know if Preem's beats that he did for jay-z's black album and rakim's cancelled release on aftermath have leeked? Remember him saying he did two tracks for both these artists but they never made it onto either of the albums for different reasons...

Thanks in advance

He won't let them leak, he can still sell them. If he hasn't already.
