I say BOY. And not just because it's fresh on my mind. I'm thinking back, and Breakaway was obviously for a movie. Not THAT impressive. Ya know? Then Miss Independent, sure, it's great, but it's not like moving and emotionally attractive. Does that make sense?
Then, SUBG was definitly a fun song. Loud song, loud video.
The competition comes in with Behind These Hazel Eyes and Because of You. Sure, BTHE was deep, beautifully put together, and just altogether awesome, but with Because of You, the relatabilities are ENDLESS. Literally.

Sorry, I ramble. Always. I'll stop now. lol
