While I can’t proclaim to have checked out every MySpace or Facebook page of each of the 40 or 50 prospective Idol contestants this season, I can tell you that — so far — one stands out.

Cardin Lee McKinney lists india.arie, Corinne Bailey Rae, Joni Mitchell, Floetry and others as her primary influences. I note these particular influences cited by the Nashville resident because they seem to associate most tightly with the sound of her music.

And that sound is highly, highly polished with a smoky, soft vocal that reminds me of, perhaps, Colbie Caillat. In fact, the first tune on her MySpace page, called “Teach Me,” is good enough that I would personally buy it right now.

Last season, I perused all the MySpace pages, and only found one with music I liked: Chris Sligh. Sure, most of these singers haven’t spent big money on demos or have a ton of serious songwriting experience, but I think you can take quite a bit about the artists they become from listening to their music right now.

And for Cardin Lee McKinney, it portends a ton of potential and, dare I say, greatness.

On the other hand, some of the forums suggest she didn’t do that great in Hollywood. However, the music doesn’t lie, and this young woman has something well beyond anything I’ve heard from any of the other contestants thus far.
