I was reading with interest that Seamus Heaney is a big fan of Eminem.
He said "Eminem has created a sense of what is possible. He has sent a voltage around a generation. He has done this not just through his subversive attitude but his verbal energy."

He was named second most powerful celebrity on the planet, by Forbes. He also won an Oscar for Lose Yourself. This was 2003, so I am completely behind the times. But here is Lose Yourself. I like the images with the lines. (Warning. There is swearing.) Love it or hate it...
