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

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

I'd say Rhythm of Amore da Plain White T's o Missing da Evanescence.

I say sicuro, cassetta di sicurezza & Sound, Haunted, and Enchanted. All are da Taylor veloce, swift (pure coincidence).

With Swift's Enchanted, add the reply song of Come d’incanto da Owl City so it can be like some kind of set.
