I still have to wait a long time for the video to load in the Mpv cache, and sometimes I want a bunch of videos to watch later (or watch multiple times if they’re educational). In which case, I either open up a bunch of videos in their own mpv windows and they all load while I’m watching the first one, or I download them while I’m doing something else.

But loading a bunch of mpv windows is heavier than a bunch of terminals running yt-dlp (and I could also just switch to using tmux… which I probably should get around to at some point).
