Sources close to negotiations have confirmed to Billboard that both artists will be a part of the music service, though in which form is still unknown.

Last week, the New York Post reported that Drake, Pharrell and David Guetta would lead a group of celebrity “guest DJs” for the revamped iTunes Radio.

It was also reported by the NYP that the OVO rapper would be paid $19 million for the deal. “Apple doesn’t normally pay artists for those types of collaborations,” a source said to Billboard, denying that information.

Drake was also one of the 16 artists/partners of Jay Z’s TIDAL service, but at the last minute dropped out, as late as two days before the star-studded launch event in New York back in March.
