Many songs that have dropped off the chart aren't mentioned

I have noticed that sometimes songs fall off the chart, but they aren’t mentioned in the “This Week’s Drop” part. I realize that sometimes a song will fall off the chart completely and not just off of the Top 40, but instead of just not mentioning it, I would put the previous placement from the week before and just dashes indicating that it dropped off the chart completely. You have done that already in many places, but the 1970s are really bad in terms of not acknowledging a song that dropped out of the chart completely. I was just wondering.

I noticed that, too. It makes me batty not knowing what had just fallen out the week prior. That’s one of my many long-term projects I want to tackle.
