Travel through the last 100 years to discover which summer songs were either released or peaked in popularity during the summer of their respective years. Some are about the summer or the stuff of summer: parties, picnics, fleeting love, nostalgia or fun. Some have that summer feeling in sound alone. Many are relevant to their times. Some have become standards. Some annoy, like a sticky day with too many mosquitoes. Others slow down time, like an unexpected breeze one hopes will never stop.
