I'm having my songs pre-mixed by a DJ friend and put on several CD's. My WC gave me a very specific time chart so I know how much time I need to cover for the pre-ceremony cocktails, ceremony, post-ceremony cocktail hour, dinner, and reception. Ask yours if that info is available.
I'm giving instructions to the person playing them for me and labeling discs in English & Spanish as well - ceremony, cocktail, dinner, reception1, reception2, etc. Someone told me itunes plays songs back to back so there are no pauses between songs, I think that was what you were referring to. I'm not sure if that is recordable though, but it's worth looking into.
