Bad songs on the Radio tend to do it for me, end up with something stupid like the Cheeky Girls in my head and curse them cause i can't remember what detail i was gonna do on some guys arm or something lol
Within the Epic battle of the fates the Shadow and the Angel will meet. With it will harbinger the very fight of good vs evil!
