I never recommend using any ipods at any weddings because there is always the possibility they could fail. I believe the best way is to have the DJ do it for you or if you want to save some money use a computer over a ipod. There are a some
times that it has worked to use ipods but I wouldnt trust it to be safe.
If you do use the ipod I agree with the idea of having someone who has one and knows how to use it for sure. Make a playlist with all the songs you want to use in order. Explaining the music order to the person doing it because people seems to
often get confused. This is your ceremony and its such an important day so make sure you have someone you trust to do this and have them test it long before the wedding.
It would look tacky to me and my friends to see someone use a ipod for a ceremony however we are all DJs and sound techs. lol I'm sure most people would never notice unless someone messes up, then everyone will know! I dont want that to happen
to anyone!
Hope you have a great wedding!
