Discord has begun testing youtube integration only weeks after google bought youtube, took down 2 discord music bots. Integration has begun to surface in a small number of servers today as part of what looks to be a fresh test of a collaboration of discord-youtube on discord. It is particularly developed for youtube, allowing discord users to construct a playlist of videos by searching for or pasting urls from youtube. You may even enable a remote button which allows other members on discord to control the playback. Many people use https://loader.to to download videos or music from youtube.
