Jason, from Miami, started his career writing songs for the likes of P Diddy, Lil Wayne, and Sean Kingston.
Dance act Example was knocked down one place to number two with Changed The Way You Kiss Me, while Calvin Harris featuring Kelis was down one to three with Bounce.
The second new entry in the Top 10 was Badman Riddim (Jump) from Dutch dirty house DJ and producer Vato Gonzalez.
The track features UK hip hop and grime collective Foreign Beggars and went straight in at number seven.
In the album chart, Lady Gaga's Born This Way bounced back to the summit for a second stint at number one. The album spent the last two weeks at number three but hit the top spot for two weeks when it was released in May.
Adele still had two albums in the top five, 21 at number two and 19 at number five.
