Drake set to release song featuring Michael Jackson.

Drake is about to set the music world on fire with his new single.  The song is called "Doesn't Matter To Me" featuring Michael Jackson.  First of all how the heck did he get that vocal?  How did he get permission to use it?  Who gave it to him?  So many questions come to mind with this single.  This single will and has out Drake in a league all by himself.  I do not know one rapper who was able to get an unreleased vocal track from Michael Jackson.  Yes the single has been out and it's been heard but they are saying Drake is set to pump this single next and hope it breaks another Billboard record.
