Closest I've come is hearing Give You What You Like and Fly (I was shocked both times!) NEVER EVER thaught I would hear those on the radio here in South Africa, and in the same store on different days no less ha ha. But those two don't really count.
I know i've heard a GL song at the store a few years ago. Can't remember which one it was since I barelly ever listen to that album. I think it was Not Enough or maybe Stop standing there. I guess a staff member liked Avril and put it in the playlist
