JAY-Z is expected to sign a $20 million deal with Samsung to promote his Roc Nation acts, via a smart-phone music service.

The rap star is rumoured to be setting up a music streaming service to help promote acts signed to his Roc Nation label — including Rita Ora, Alexis Jordan and J.Cole — via the company’s Smartphones.
A source told the New York Post: “The eight-figure deal will be inked in the next few weeks, and is the biggest of its kind.
“You can speculate that he’ll want to develop some kind of new music-streaming service to promote his acts and music on mobile devices.”
The 43-year-old star and his wife, Beyoncé, were spotted backstage at the Hot 97’s Sunday Summer Jam at MetLife Stadium last weekend, which was billed as ‘The Biggest Hip-Hop Show on Earth’.
The ‘power couple’ then partied at New York City’s W.i.P. club until 3:30am last Monday,  holding court at two tables with rappers Fabolous, Miguel, Wale, Meek Mill, Busta Rhymes and Omarion.
Jay-Z isn’t the only one making mega bucks from business deals in his family. Beyoncé signed a $50 million contract to become the new face of Pepsi last year.
The lucrative deal saw her grace a series of limited-edition cans of the fizzy drink, with Pepsi also sponsoring many of her concerts and helping promote her forthcoming fifth studio album, set for release in November. (BangShowbiz)
