I can't remember what music we had -- but we had a crappy DJ. We chose him based off of recommendations from acquaintances. Trouble is, they didn't use him for a wedding, but instead random parties.
I do remember we used some Josh Groban music for the ceremony which sounded great and we danced to "our son", "I Knew I Loved You" by Savage Garden -- (Truly Madly Deeply is another great Savage Garden ballad)
