Not to be outdone by Pharrell (Although, aren't we all outdone by Pharrell at all times?), Rick Ross's new album, Mastermind, is also streaming at iTunes Radio before its official release next week. Ross features the likes of Kanye West, the Weeknd, Lil Wayne, and Big Sean on tracks produced by Scott Storch, Mike WiLL Made It, Diddy, and DJ Khaled. Looks like Maybach Music called in all the favors this time around. Check out Ross's duet with Jay Z below, and you can stream the full album at iTunes Radio.
