Long time ago, when there was not DAW or desk automation, what mixers-engineers did was to break down a song into one minute parts and mix this and then glue together the final master track. You salute such efforts today when people have DAWs and don’t know how to mix or when to stop mixing.
Anyway there are no fixed rules, do whatever sounds good.
I just finished Ken Scott’s autobiography, he recorded Beatles, early day Bowie, Missing Persons and much more. Fun book about early day mixing/production voes.
Anyway, there are so many ways to do this. I think it has to do with carefully knowing what the crowd anticipates or subtly get them to anticipate tracks and breakdowns. Me thinks the best is to go to any of your favorite bigger star DJ shows and see how they do it.
My favorite trick is to quickly switch the song to something else if the audience don’t dig it. So instead of playing it a longer time period it just becomes a smaller interluded loop mixed with something else, hehehe.
