Ear worm (or, Dallas: Day 64)

It bugs me when the last song I hear on the radio before I turn off my truck and get out to start a 12-hour workday happens to be a sucky song. This morning it was "Miss Murder" or whatever it's called.
All day it was playing on loop in my head, "Hey, Ms. Murder, blahblahblah." I couldn't turn it off.
I would've much preferred the Mini-Sirloin Burgers jingle instead.
