Good question...thanks Chuck for chiming in!
I have just made a list of 44 songs that I like, with some 'must plays' off that due to timing. Our reception will only be 2.5 hrs, so I labeled some as 'during dinner' which is softer, then 'dancing' which is both slow and fast/fun. Then,
of course, the 'must haves' like first dance, father/daughter etc.
I am really big into music, so I too, wanted to ensure certain ones were there, but I guess I should tell my DJ that I dont mind if he goes off track if need be.
