That depends on your preference. If you as the client are happy with requests, I am happy to take your guests' requests. Under most circumstances, requests are great, but it’s also important to remember to allow enough leeway for me to also read the crowd on the day.
Live music requests are also possible. If it’s a song we know, we will happily play it. If we don’t, we will endeavor to play something similar or from a similar genre or style.
