Heard this song at the underground in chicago. Had this whistling in it that was infectious and the song would build up stop then some dude would say something and the beat would come crashing in again. It was definitely a crowd pleaser. No idea what it was called or what the dude said but I can't that beat and whistling out of my head. HELP!!

Maybe it is Juelz Santana - There It Go (The Whistle Song). Here is the link to the video: Juelz Santana - There It Go (The Whistle Song) - YouTube (http://www.youtube.com/watch?v=EGMOD3rVsK8). Hopefully this is the song your looking for.
