H.A.M.

If ever you needed proof that the world's a more harmonious place when clever clogs rappers aren't beefing with each other, 'H.A.M.' is it. The 865 millionth collaboration between mad scientist Kanye and businessman extraordinaire Jay-Z is hilariously pompous. (Yes, that is an operatic interlude! Well spotted!). But it's also got a killer hook and naughty abbreviation on its side. See? You can be Hard As a Muthafucka and still have friends.
