Ed Sheeran do make pretty awesome music. That being said I always wondered what fills the gap in hearing of the deaf. Fascinating to see the connection between many seemingly unrelated event and the body's reaction to it. The subconscious plays a major role in most of the daily going ons. I could totally relate to the earworm effects which I think is fantastic as the brain fills in those missing gaps making it easier to listen to those favorite tracks without actually listening to every word.
