Be prepared to feel old: today is Eminem's 40th birthday. That's right, Slim Shady is officially middle-aged (or close to it at least). Once we stopped examining the cruel, fleeting nature of youth, we decided the best way to celebrate was by listening to some of Mr. Mathers' biggest hits on our Happy Birthday, Eminem playlist. From "My Name Is" to "Love the Way You Lie," we've got you covered. So, enjoy. And Happy birthday, Marshall!
