Does anyone have an idea of the name of the artist or the song title which has 4 gunshots and then a "kerching"-like sound of the reloading of a gun?
I believe the woman sings with a london accent.

Much appreciated if you spend time over my query :)

Audio Bullys/Nancy Sinatra -Shot me down, maybe?

Nope that's not the one... I found out, its Paper Planes by M.I.A.
Thanks very much though :)
