I need songs for my wedding!!!!?

I need good songs for my wedding procession, recession, lighting of the unity candles, and a recessional. Prelude would be good too!!!! I was thinking Finally by Fergie for the procession. And my fiance and I were thinking From this moment by Shania Twain for our 1st dance. We would like songs that are sort of different, i.e. not the usual wedding march. I need help plzz!!! Thanx
