Song in Head

I almost always have a song playing in my head for whatever reason. It's typically the last song I heard on the radio or on iTunes or whatever. Have you ever had a song in your head that you can't get out? That's me right now. For whatever reason, I have Arianna Grande's song, "Problem" stuck in my head. I have listened to several other songs throughout the day, but this one will not leave my head. It's been in my head pretty much all day. It's an annoying song that I don't like so there's no reason for it to be in my head. Hopefully it will be out of it when I wake up tomorrow and take my run while listening to my iPod.
