Continuing to work backwards, into the top 20:
#20 - Pretenders - Pretenders
Released January 20, 1980, the debut from the Pretenders just barely qualifies for Best Of The 80's. But close enough, it is. This came out in the spreng of my sophmore year of college, and it really caught everyone's attention. From pretty pop songs like "Brass In Pocket" and "Kid" to punky "The Wait" and "Precious", this was not boring.
And of course, there's "Space Invaders" with the sounds of the (then dominant) Space Invaders video game in the background (at the end). I dropped too many quarters into Space Invaders in that time period, the song really hooked me.
