I recently got this mix from somewher and it says its from Paul Van Dyk party mix 2k3 in Matrix club in Florida. Anyway i got the sample for you guys to try and guess, let me know if it rings a bell. It's more "techy" than "trancy" but it's a real party booster, so i leave the challenge to you guys

try with Air Bureau - "Don't expect me (to forget you)"! But I don't know if it is the original mix! the vocals from the start are from this track and paul played it sometimes.

thanks for the help, it's full name actually is
Aircrash Bureau - Don't expect me.

Thanks again for setting me on the right track to find this song
