Crowds!
I had found that crowd sample tiring before, and now that you have it playing throughout your entire song, I'm even more tired of it. IMO, that thing should be used for specific moments in the song, otherwise it loses its power. No crowd in real life would be cheering that long that consistently. :P
Otherwise, it's an alright song. Kinda muddy because you don't have any highpass filtering on the things that need it (like the lead synth), but it's a pretty solid house song. Repetitive, predictable, and not original, but just what the doctor ordered for the standard clubber.
