We've already seen Survivor and Big Brother go the all-star route. And The Amazing Race is getting set to kick off their own version. Heck, it seems like every time I click by MTV there is another show filled with past Road Rules and Real World cast members. So why not American Idol?

According to TV Guide, Idol producer Nigel Lythgoe is trying to sell Fox on the concept. It's part of the planned songwriting competition. Lythgoe's idea is to narrow those entries down to ten songs and then bring in ten former Idol contestants to sing the songs on the show.

I'm not an Idol fan, but I have to say, that's a solid idea. I'm guessing they won't be able to get Kelly Clarkson, and chances are Jennifer Hudson won't be involved. But assuming that they can manage to get ten of the more popular contestants, this should make for another huge week of ratings. And an American Idol All-Stars CD... And an American Idol All-Stars Special Edition DVD... And... good grief, Idol is just a machine. At this point it's rivaled only by the power of Harry Potter.
