Celebrity couples are pulling the plug on traditional music options and playing their iPods instead. Actress Kathleen Robertson rented a speaker system and designated Robertson's brother-in-law master of ceremonies. Actress Diane Neal didn't want to take a chance on a local DJ for their wedding in the Dominican Republic, so they also hooked up their iPods to a stereo system. Ari Abramowitz, author of Pockit Rockit (Music Guru, $13), suggests allowing plenty of time to assemble your playlists, making separate ones for the ceremony, cocktail hour, dinner and dancing. And since you're in charge, you can safely avoid "Macarena."
