Unfortunately, mine wouldn't be a metal song. It's a toss-up between Sting - "Fields of Gold" (the song my wife and I danced to at our wedding) and U2 - "With or Without You" (the song we wanted to dance to but didn't choose because we didn't feel like explaining 5,684,238,965 times why we picked a song with those lyrics to dance to at our wedding).
