Just something I noticed

Well, after the class today I went to the grocery store with my grandma. I was walking through the aisles when I noticed something strange.........

You know how a lot of stores play music over their speakers, right? While as I'm walking through the aisles I started listening to the music.... And I started realizing that every few aisles it was a new song. And I don't mean like a new song playing after the other one.... I mean they were playing completely different things over different speakers! And I thought that was really strange! Especially standing right between two.... Crazy!
