What song do tu think fits Roxas and Xion's relationship the best?

I think Until my Last Breathe por Evenscence.( I'm not sure I spelt that right...)

I'd say Rhythm of amor por Plain White T's o Missing por Evanescence.

I say seguro & Sound, Haunted, and Enchanted. All are por Taylor rápido, swift (pure coincidence).

With Swift's Enchanted, add the reply song of encantada por Owl City so it can be like some kind of set.
