Thanks a lot for a help!

I hope that was doors slamming and not gunshots!

Perhaps this:

Nicole Scherzinger - Everybody

Nop its not that one. I think that my song is quite old one at least 5 or more years cause i heard it couple of times previously. And yes those slamming was doors not gunshots, im fine thanks a lot Any more guesses?
