Musicologists will be quick to interject that "Hurt" was originally a hit for Nine Inch Nails back in 1994, but when Johnny Cash took a stab at it in 2002 at the hands of producer Rick Rubin, he recorded what many consider to be the definitive version. Cash took Trent Reznor’s industrial soundscape about a tortured soul and stripped it bare, save for an acoustic guitar. "That song isn’t mine anymore," admitted Reznor. Instead, the song, which can partially be interpreted as a lament about the ravages of drug addiction, belongs to Cash, who sacrifices himself as the prime example. He died less than a year later.
