Its that song on your iPod or Mp3 device thats louder than the rest. Usually this songs comes up in the most random time, especially when your trying to sleep.
Usually you want to erase the song but you cant since you like it.
After a long day at the office, John gets home and eats a small meal. After that he heads towards bed with his iPod. He goes on shuffle and starts dozing off. Around 2am that Random Loud Song comes on and scares the sleep out of him.
