Musician Trent Reznor has hit out at rock rival Gene Simmons, accusing him of playing up to his younger audience. The Nine Inch Nails rocker insists it's more important for him to keep his musical credibility than be popular. He says, "I hope I don't fall into that trap. I loved Kiss when I was growing up. At puberty they were there to rescue me from a life of athleticism - failed athleticism. "But I would hope that I never become Gene Simmons: where as an X-year-old man I'm singing about making out with chicks in the back of a car because the kids want that. That's not how I see my role as an artist."
