You say what song is stuck in your head now,title and artist(if you want you can write album,too).Not sure if it already exists,but let's try!!I'll start:The song stuck in my head now is My Happy Ending by Avril Lavigne,Album Under My Skin.
For some reason the "Eminence Front" by The Who is stuck in my head. I listened to it early, but didn't really start thinking about it until a few minutes ago.
