You don’t have to choose every song for your DJ. Provide them with a few must play songs, 5 or 10. Then you can add selections to play if time permits.
You can also let your DJ know whether they can take requests from guests. Of course you can supply a do not play list as well.
Be sure to enjoy the “task” of picking your songs. Doing so will help to keep your planning stress-free? – TT
