To me it sounds like a rhythmic beat that DJ's sometimes between 2 songs they can't really mix well, in order to go from one to another.
I have the impression that the intro goes until 4'10" and there something seems to start.
That synth lead is heard earlier already but slightly muted.
I would skip that first part and start directly around 4'10" (with the fat beat you hear at 1'45"), but then build up that lead synth and add more melodies. It's a bit too repetitive to my taste.
