I love this idea from Jessie:
I just wanted another great idea a friend of mine did recently at her wedding which was a roaring success. On the r.s.v.p. card they included:
Number of guests attending: _____
Song request #1:__________
Song request #2:__________
Instead of paying for an expensive d.j., they hooked up their laptop, after downloading everybody's tunes and had a friend play the list. The dance floor was packed all night long!
