What matters most
A playlist plays what you set; a DJ makes live timing calls — stretching a full floor, cutting a flat song, reading when to lift the room.
Points to work through
- Choose a DJ when the event has speeches, entrances or awards that need music started and stopped on a human cue.
- A playlist can work for short, low-interaction gatherings where reliable background music is enough.
- If you go playlist-only, still test playback end to end: files, device, cable, backup device and the person who presses play.
- Decide who takes requests: with a playlist, nobody — so set expectations with guests in advance.
- Budget the hidden cost of "just a playlist": someone competent must own the sound system and the room all night.
