Everyone has their favorite CD collection or personal playlist saved in their iPod. Since we're average everyday people, I was wondering, who do the top artists on FUN 107 listen to?

Does Lady Gaga love listening to Rihanna or some weird group that nobody has heard of as she heads to the gym? Does Justin Bieber listen to his girlfriend Selena Gomez while heading to a concert that has thousands of screaming Belieber fans? Or, are some of today's artists so into themselves that they have become their own fans?

On a related subject, I have asked myself the same question about movie stars and TV stars. Do they own movies starring just them, or do they forget who they are for a moment and become a fan themselves?
