On the flip side, when I was a DJ I would have a couple come in and want to pick every song I could play. All Stevie Ray, or Blues Or rap. Absolutely no Sinatra, no polka, no country, no big band etc. I would try to tell them that they are going to be busy but the relatives and parents need to be entertained and will have requests, And they hire me to entertain them if I can't do that I tell them I am aready booked for that day.
I learned to turn those jobs down because you will please no one and actually damage your reputation.
