Bismillah

Thank you for your question. Enjoining the good and forbidden the evil is dependent on the effectiveness of your actions or words, not on whether the person will feel bad for a time, even if that be your own parents. Rather, what is important is to maintain respect and gentleness if you think your message will reach open ears. 
 

As for playing haram music at your wedding you can state quite clearly that you would be opposed to that.

May you always be successful
