Start off writing yall favorite songs from every era! Start eliminating anything with cuss words or anything dealing with broken hearts or death or sexual things in it...The first few songs in the reception should be upbeat yet chilled out music -something were people can mingle and eat (people love to hum and move while eating). The second part which should be around after you take pictures and cut cakes etc should be something with groove to get people ready to dance (line dancing etc) Then you get to the jamming parts of the night/day. You don't want to play anything slow here, you will bore people and they will leave quickly. You want them to have a great time - I can compose a few songs if you like and give you a list
