I have played a few weddings and other events where I have received future Bookings from parents of the Newlyweds, Grandparents and Guests from events who have said that they enjoyed my song selections. It is a great feeling when you receive Contacts and clients for future bookings when the client says that they say me play at so & so's event. It happens quite often. This is reason that I do not play songs that contain profanity. (Kids)
I'm not suggesting you change your values to accommodate a request. And I don't play dirty edits at a wedding either.
All I'm suggesting is that if the CEO asks for something, they get priority of what I can possibly do. And at a wedding I will consider the bride the CEO.
If nobody else likes what I do at her wedding because I did what she asked... That isn't my preference, but I am willing to take those instructions and go down with the ship.
Of course, most of my clients hire me because they want a great party and for their guests to enjoy it. It's rare that a real conflict comes up. But I know whose side I'm on if it does.
