Help : Song with Chorus about opening safe

[dirtybarry]

I cannot remember this song! It's probably from about 5 years ago. All i remember is that it was a female singer, quite beaty, the lyrics in the chrous are about opening the combination to a safe "34 right 22 left..." etc

I heard it on my mp3 player whilst walking through the city. thought it sounded great. vowed to check what it was later. lost the mp3 player and have been trying to recall it ever since. Help!
