The problem I see with video -or audios, or posts, or whatever content- recommendations is that from suggesting content based on the title to suggesting content in order to change the viewer mind, there is a very little step. That's what major social platforms do and that's why most people should stop using them. That is not, yet, the case on DTube or DSound, but if they implemented it, the probability to end suggesting content to change minds is very high.

DTube Analytics could be good. But only if it allows you to analize information extracted from the blockchain. In the case of location, that would be mostly useless or inacurate. But if the tool shows you anonimized reports about the SP of your upvoters or the categories they upvote the most, that could be not good but HUGE.
