Okay so maybe I got a little giddy when I recognized the song and jumped on twitter to say so .. but the short clip of his performance struck me as just plain odd .. although he obviously has great taste in music. :)  Found it interesting that Blake was the only one who turned his chair too. 
I don't follow any of the other sort-of-maybe-about-music shows, but actually do like The Voice so will be watching to see how Mr. Fuente does on the show.
