I have never set a minimum OR maximum number of requests. For some clients, it's all they can do to pick a first dance, and then they instruct me to "just play what people like"! For some clients, I have received spread sheets of every song they have ever liked, sometimes hundreds of tunes. That tells me a lot about those clients, and informs the conversation and planning with them. "Wow! You two really love music and music is obviously very important to you. There are some really good ones here, but, I won't have time to play most of these. (Explain the whole 17 songs an hour average here IF needed) Because I want to make sure I get it right, can you help me prioritize a few MUST PLAYS. If you can tell me (Groom) top picks, and (Bride) top picks .... and any special family or friends favorites, I can take it from there." Once I have some priority to work from, I can then try to decide if some of the original list is perfect for ceremony, or cocktails or dinner or whatever. I make it clear I appreciate their choices (I do), and also clear there is no way they will all get played. With a rare few exceptions, this has worked great for lots of years and hundreds of receptions. By the way, most couples are in the middle - a few "Must Plays" a few "Don't Plays" and a bunch of generalities (for example "we like current, and don't like country"). So, in summary, do what works for you, but make sure you communicate with your couple, so you both have clear and realistic expectations of what will happen with all of those requests!
