So, it's a great, comprehensive list, but it doesn't give enough data. But the problem with those lists is they don't include the number of views of each video and the dates they were posted, which I need. But if I want more, the channel has three more playlists that go all the way down to 75M views, a total of 2,051 videos. That list currently has 537 videos, which is plenty. (Over 450M views) from the YouTube channel, MyTop100Videos.The reference given for Wikipedia's list is the playlist, Most Viewed Videos of All Time

The YouTube documentation states that StackOverflow is the official venue for support on the YouTube APIs, so I hope we can get an official response from YouTube on what's going on here, as well as responses from knowledgeable folks outside of Google (which owns YouTube). The question then is, how can such a list be generated? The information below shows that such a list can apparently not be obtained from the YouTube Data API, and apparently not from any YouTube API. Wikipedia gives a list of the top 30, which is still not much.

A lot of websites list the top ten or twenty, but I want a lot more than that. I want to get a list of the most-viewed videos on YouTube.
