Can I give you a song playlist for the event?

Yes, of course.
We normally ask for a list of song choices for important parts of the wedding, such as the Grand Entrance or Cake Cutting.
You can also give us a list of other songs too, such as a dedication song(s), any songs that are sentimental to you both, personal favorites, etc.
Otherwise you can leave everything to us and we can select what we feel is a good mix of songs, both old and new.
