The much-anticipated collaboration album between Kanye West and Jay-Z is set for a March release, and today brings the first single. It's not the first time that 'Ye and Jay have joined forces, and the verses of "H.A.M." sound almost like a battle between the rapping powerhouses. It tends more on the side of gritty and intense than infectious and catchy, but it's definitely worth a listen (if nothing else, to get confirmation on what "H.A.M." stands for).
