this should probably be in the CP Confessional thread:
we danced to "I'll Be Loving You Forever" - New Kids on the Block for our first dance.
...and I picked it

(i picked all the songs)
highlights:
bride's entrance to ceremony: Ice Dance - Danny Elfman (Edward Scissorhands)
ceremony march: Hill Valley 2015 - Alan Silvestri (Back to the Future)
grand entrance: Throne Room - John Williams (Star Wars)
cake cutting: Breakfast Machine - Danny Elfman (Pee-Wee's Big Adventure)
flower toss: Gonna Fly Now - Bill Conti (Rocky)
garter toss: Raider's March - John Williams (Raiders of the Lost Ark)
groom/mom dance: Mama - Spice Girls
there were others, cannot remember off the top of my head. most of the songs i chose were from movie soundtracks. the traditional dancing songs were mostly 80's pop stuff. spent a few weeks going through my music to get the songs.
I tried to make it fun for the audience with music since most wedding music is the same...YMCA, chicken dance, the hustle...none of which i allowed to be played.
