There are so many components that go in to choosing the music for your wedding. You have to think about the time, location, style, and of course the guests and then there is deciding if you want to have a DJ or a band. My number one suggestion is no matter what you decide make sure you meet the band face to face, listen to their music and if possible hear them play or spin live.
After you decide on style and type start making a lists of songs and types of songs that you want to be played on your special day, keeping in mind your guests who are attending and what type of music they like as well. In order to assure your dance floor is packed pick music that will play to everyone. You can still have your own music style, but get Grandma and Grandpa shaking it on the dance floor with some oldies that everyone love to hear!
Make sure to start out the evening with a bang when the wedding party enters and continue all the way till the end with the last song.
