I don't quite understand what you mean.
Say, I want to do an event "Guess the song"
I ask a DJ to play a defined playlist on several conditions.
like.
/ad Guess the song and win 5K (and/or via radio)
DJ plays song on my command when time starts.
after 30 seconds song stops by DJ via command.
Declare winner via /ad and/or radio
cycle continues till playlist or time is up.
