Reply to Need Some Advice

This goes to any DJ out there, not specifically any with a certain set up but... I have been DJ'ing for 3 years, mainly into tech house, minimal, dub tech, dub reggae, house and dark minimal. My only problem is, My brother is having a wedding this summer and He hasn't really given me a list of songs or any suggestions on how to approach this. I've never EVER Dj'd a wedding before and don't really know how to, if anyone has any suggestions like genre suggestions, transition ideas (if they apply), and what kind of things I should expect; Please Post below!

Thank you so much.
