Freetube is great for regular video playback but isn’t a great music player, and it’s not super stable on android for me. None of the YouTube music apps like outertune have video. Meanwhile some way to keep everything organized from my multiple music sources would be cool too.
If you have an idea of what you want to listen to ahead of time you could make a playlist and use yt-dlp to download it all. Then play it in the music player of your choice.
