The greatest hits are always anonymous, anyways

I decided I would make a playlist of 20 songs that I enjoy listening to on the current hits channels on YouTube. The problem I quickly discovered is that, simply put, I don't know names or artists for many songs. I managed to scrape together a playlist, but, I had to get out of this decade and go back some. (I did not want to repeat artists, either, which made my list more difficult.)
