All this music in my head

I'm convinced that inside my head I have a jukebox (or maybe its modern and its some type of mp3 player). Lately, every morning that I wake up, the first thing that pops into my head is a song, and its not a song that I have heard to recently, its some random song. For instance, this morning was Belinda Carlisle's "Mad about you". WHAT? I actually had to look up who sings that song because I had no idea. I'm wondering if its because of a recurring dream or what. Maybe my subconscious is telling me that I should be a DJ.

This morning's song: Reminisce by Mary J. Blige.
