Martin Luther
Counting to 100 isn't a bad idea when the plumbing clogs five minutes before the guests arrive. But it might be more fun to rap, rhyme, or say a mantra when you're at wit's end and ready to internally combust.

Martin Luther, whose new album, Rebel Soul Music, comes out in October, wrote a special rap just for O, The Oprah Magazine. Listen to it, learn it, and get ready to use it next time you need to blow some serious steam.
