Yesterday it was the song they use at the end of the movie The Void, something I only remember one (repeated) line from - "by and by, we're going to see the king." Would make more sense if the movie explained more. But in any case, I had a heck of a time getting that out of my head (yes, just the one line repeating - and yes, it was driving me bonkers).
Today, "Symphony of Destruction" by Megadeth. I'm not a big Megadeth fan, but it was on the radio when we were in the car this morning, and now it's stuck in my head.
