Johnny Cash is one of the most powerful singer/song-writers that has ever lived. The live that he lived, and the stories that he's told via his music, are beautiful. He had quite the journey, and that's why his cover of Nine Inch Nail's 'Hurt' is so magnetic and poignant. He didn't write the song, but you know he means every word that he sings. And you can tell by looking into his eyes that there's something inside of the man that, in his final days, he was trying to get out.
