I have been a big fan of both Blake and Jordin from the beginning. They've always been my top 2 and going into last night I didn't care who won. I still feel that way, but as soon as Jordin sang the first line of the last song, I said to myself, she just won.
It might not be fair to Blake that the outcome will be decided on a song that he'd never record, but I think he really lost it by doing another Maroon 5 song as his "never done before" choice. He had just done one last week and he didn't sing this one as well. He should have chosen something more "fresh" for him that showcased his talents better. I don't think Jordin sang the Christina Aguilera song so well, but it still was better than Blake's Maroon 5 song. They both performed their "previously done" song extremely well.
Blake just had more to overcome or "sell" to the public and his best chance was the Maroon 5 song - and he whiffed.
I think he may sell more records though.
