This question will put a date on those who reply, but that's what will make it fun.
What songs, when you hear them, make you think of your high-school days?
For me, if I hear any of the following songs, I think of my high-school days.
Pink Floyd - The Wall
Rough Trade - High School Confidential
Teenage Head - Disgusteen
April Wine - I Like to Rock
Van Halen - Jaimie's Crying
Jim Carroll Band - People who died
Judas Priest - You got another thing comin

That's just a handful.
