Alright well I've downloaded and listened to just about every single Paul van Dyk song on a released CD and have not figured out the name of this song. I have it on a 1 hour 17 minute mix named "Gatecrasher Classics - 2001". I know it is Paul van Dyk because during the middle of the song a guy on the microphone says "...We're rockin' away to Paul van Dyk". I know this isn't that descriptive but hopefully someone can help me out... here is a small portion of the song available for download: http://www.mediafire.com/?lymsdxzmb01
