Taken from the American Idol boards:

Hehehe...for the second night in a row, Mystery won in a heads up competition of songs with over 70 percent of the vote on Detroit radio station WDVD.

It will be on again tomorrow night at 8 o'clock and if it wins, it will enter their rotation. This should answer your question as to whether it's a single or not. I told you it was and I've told y'all a video is coming in about two weeks. Don't know what the video contains but I can tell you there will be one.
