Wrapping up the top 20 songs released in 1985 proved to be really tough. All the prior tracks had enormous cred to stake their claim to the top spot, but in the end, this one track managed to do it. It is the defining song of this man’s career, and has managed to elude its encapsulation by the 80s decade sound, being a huge rock anthem and a song dedicated to all those artists who tried to make it big but decided other things in life were more important. The #1 song turning 40 years old this year is – Summer of ’69 by Bryan Adams.
