The couple can pick the important songs such as the first dance song and cake cutting song and can trust the dj to play what he thinks would be good. Some couples can just give an outline and let the dj run free. Since some couples are super busy and would want to dj to do all the leg work. Other couples may incorporate a do not play list. Also, the couple can give a list of must play songs for the wedding. Dj would be able to incorporate those must play songs throughout the night.
The best weddings I have been a part of was when couples gave a list to the dj. Often times the couple does not know when to start. With my couples I give them a list of popular songs played at weddings. Music ranges from 80s to pop to jazz to rock. From the list, the couple would send their selections. The couple is also free to include songs that are not on that list. From the selections, the dj can continue the vibe of the event with the songs that they were given.
Also communicate is key with your dj so the dj can see what kind of music to be played at the wedding. The dj can use the playlist the couple gives them as the foundation and play songs that would fit in that category. Also, as a couple, it’s good to be specific with the music requests. An example would be if the couple wants old love songs but in reality, they wanted Motown.
In a nutshell, the couple should help the dj build a list and the dj uses that as the foundation.
