Last night's American Idol final made one thing clear to me -- 17-year-old Jordin Sparks should win. And if DialIdol is an accurate indicator, Sparks has the votes -- with a score of 45 to Blake Lewis's 30.

I've never heard of DialiIdol, but according to its website, DialIdol's software speed dials votes for Idol contestants. DialIdol measures the busy signal to predict who will be voted off and it claims that it was 87% accurate for American Idol's fifth season. Moreover, DialIdol claims to have accurately predicted the winner of every show it has covered.

While I enjoyed the story about how Lewis started "beatboxing" because his father wouldn't buy him a drum set, I thought Sparks demonstrated that she was the better singer. She turned the mediocre winner of the songwriting competition -- This Is My Now -- into a tear-jerker that left voters with a much better reason to vote for Sparks than did Lewis's embarrassed rendition.

So I think Sparks will win -- the big question is whether she'll have the kind of post-Idol career that Kelly Clarkson and Carrie Underwood have enjoyed -- or whether she'll fade into Taylor Hicks-like obscurity.
