I like Kris, as he's the rare contestant who would probably put out a CD that I would actually buy. No, it's not the traditional Idol pop star stuff, but there's definitely a niche for acoustic guitar guy: Matt Nathanson, Howie Day, Jon McLaughlin, Jon Foreman, that sort of thing.
But Adam's going to win. (Given that he did that version of Ring of Fire with the sitar arrangement, though, I was wondering what it would be like if he'd done All Along the Watchtower for Rock Week.)
