Google books + youtube = time travel

Sometime in the very early seventies I started listening to pop radio. I know there are songs that never lasted past their 15 minutes on the pop charts but that I want to hear again and I've thought about checking out Billboard magazine at the library to see if I can locate some of them.

Well. Google books now has full text versions of Billboard. So I've started on a quest - I started with early 1970, and I've been searching youtube for every song on Billboard's top 100. (Well, except for the ones I know well because they are still being overplayed on the radio)

I've gotten to February of 1971 so far. I've found several I recognized, but didn't know the name for, and a couple I've never heard but enjoy. I think I'm just now getting to the point where I got my very own radio and started listening to "adult" music.

This is still one of my all-time favorite love songs, and I don't think it ever got much airplay after it went off the charts.
