I have no idea who it's by and it plays on the radio everyday. It's a female and it's pop/rock. The chorus says something like "I'm not here for your entertainment...you don't really want to mess with me tonight..Just stop (blah blah blah)....before you walked into my life.....". And there's more but I'm drawing a blank right now....
Help! It's driving me crazy. Who sings it??
