1984...I was in college back then. I can't even remember most of those songs, probably because I've never listened to Top 40 radio stations.

The only songs on that list that I owned were Springsteen's "Dancing in the Dark" (from Bruce's "Born in the USA" album) and "My Ever Changing Moods" by the Style Council. I bought both of those albums when they first came out.
