I've got one of Lady Gaga's songs in my mind as a mind worm. I took a nap and woke up with this tune and words being repeated. "Beautiful, Dirty, Rich."
I'm thinking, "Bang, bang, bang, we're beautiful and dirty rich." The chorus goes on like that for a ways. Then there's a talking part. I can't think of the words but know the tune.
You know you're a CD that's been in mind when people wake up to you. And you're not even playing.
