Released in 1990, so technically it is an 80s song, if’n you subscribe to the whole notion that a decade ends in a year ending in zero.

Ah, the 80s!
Tesla - Love Song and What You Give are 2 of my favorites of all time.
Warrant - Blind Faith (not sure if it’s legitimately 80s or early 90s)
George Michael - Father Figure (personal memories cause this one to make it to my list. Thank heavens I don’t have to fit my butt in the back seat of a car anymore. 
)
Def Leppard - Hysteria
Heart - Alone
I could list many many more…but I’ll leave it at that for now.
