"One of the most important wedding songs of the day, your first dance song will be one that you remember for years to come; feelings will be forever evoked among yourselves and your guests upon hearing your first dance wedding song choice. Selecting a great first dance wedding song is important, but should not become a stressful matter, nor should it come between a bride or groom. Choosing a first dance wedding song that you both love and reflects your personalities and wedding day is, however, fundamental. Your first dance and wedding day is, after all, about you. In order to avoid disagreements over your first dance song choice, why not individually write lists of possibilities, cross referencing to see what you both love? If you can’t agree on one specific first dance wedding song, then select a couple for your first dance or pick different genres from which to choose a few first dance songs."
