Songs with sunday are mostly depressing. I enjoy listening to them on sunday. Some arn't, and I also indulge in that kind.
Add to this, then someone make it and put it on YSI
Gloomy sunday - Paul Whiteman with Johnny Hauser
Sunday morning - the velvet underground
Sunny sundae(ITS ALMOST "SUNDAY") smile - my bloody valentine
Every day is like sunday - morrissey
