I heard this song before starting out with what sounds like a guitar. It begins the intro for awhile like 10 or so seconds followed by a 3 second techno bit followed by a big HEY by a crowd of people. I've tried looking it up, but to no avail. After the HEY the techno comes up with another HEY and this goes on 3 times in a row with other stuff going on. Not sure if it's followed by the guitar thing again.
