Crazy or what ?

I've this different habit or I don't know what should I call it. I generally don't search for songs or music. But more often , some songs freeze me and strikes me in mind. And I listen to them on loop for some days and then I may be forget about them. May be this is called as 'moment freezing us', right now, I'm listening to 'Arcade Fire, Deep Blue' song, which was a credits track of the film BOYHOOD.

This isn't the first time. But I want to save this.
