There are sounds that simply are not music to the ear. To those of us who consider ourselves traditionalists, the sounds of Elvis and any late 50s, early 60s rock 'n roll is sweet; any rapper assaulting a microphone is like fingernails on a chalk board.
A sincere "Welcome home" from loved ones when you've been away for a while brings a warm, fuzzy feeling and even a tear to the eye. The sound of your dad's voice calmly saying, "Welcome back," is not soothing to the teenager who thought he had slipped unnoticed from the house after midnight for one more prowl. The accompanying feeling is anything but warm and fuzzy and there could be tears.
