odds at four mean tamyra...

The field is down to four, and that only means one thing: a shocker could be afoot.

Historically this is the week of the unexpected. In season one, Tamyra Gray looked to be a lock for the final three showdown with the other front runners Mr. Guarini and Ms. Clarkson. Little did anyone expect that upstart Nikki McKibbin would turn in two memorable performances to great reviews and Tamyra, after not missing a note throughout the season, would turn in a memorably bad rendition of New Attitude and find herself the first victim of the final four curse and the creator of a new verb.

We still refer to talented contestants waving goodbye while considerably less talented ones remain to sing another day as being tamyra'ed. And fourth place just seems to be the place where all the cool kids hang out. At least in the odd-numbered seasons.

Just ask LaToya London, who got tamyra'ed in season three by the entire state of Hawaii. Or season five's Chris Daughtry, who got blindsided by Elvis.

It's pretty much a consensus that the show is aiming for a battle of the Davids for a season seven finale. Hell, even Simon is going on the record. So that leaves Jason Castro and Syesha Mercado to battle it out for that valuable third spot, the eligibility to make the finale and, most importantly, a trip back home to parades and proclamations.

Or does it? It is an odd-numbered season, after all. And with ratings down, what better way to stir buzz than to see one of the presumed Goliaths struck down by a rock - on rock and roll night.

The spoilers are creeping in and, as usual, Jason's songs have been leaked early. There's no verification, but this source hasn't been wrong all season, and it seems Mr. Castro has chosen I Shot the Sheriff and Mr. Tamborine Man.

TMZ should have the verified song spoilers in a couple of hours, and when they're up, I'll be writing 'em down.
