I also thought the top three (+Alex) were the best--which says something about the judges and the votes, this year. . . . So . . . Yay for talented people reaching the top!
In no particular order, these are my three favorite performances from the top three contestants.
Alex: "Say Something"
And I'm sorry, but as a bonus: There is *nothing* but chemistry between these two. At the very least, I hope they remain best friends forever.
Caleb and Jena: "It's Only Love"
That is all. :)
