He may not get the media attention of a Clay or a Kelly, but season 2's Josh Gracin has carved out a solid career as a twangy country heartthrob. His eponymous 2004 debut sold an admirable 655,000 copies and spawned a No. 1 country single (''Nothin' to Lose''). And while Idol may have opened up the door for him, Gracin, 25, credits his four-year Marines stint with getting him ready for life on the road: ''The Marines taught me discipline, patience, responsibility, drive, and how to set a goal.'' He's going to be calling on those traits in the next six months as he begins a tour to promote his second album, All About Y'all, due this summer. Now, about that title: Could it be a sly dedication to Randy, Paula, and Simon? Not quite. ''It's all about how the world revolves around women,'' says Gracin, who's been married for five years to wife Ann Marie. ''It's their world. We're just living in it.''
