Anyway, if they didn't want people to be able to copy their stuff, then they shouldn't have put it on YouTube. The music industry is being as dumb as they ever where, it's fascinating that they've learned NOTHING in the past twenty years. How much money can they possibly lose on youtube-dl vs. how much money they continue the scam out of artists.
At this point who doesn't have a subscription to a streaming service? Those who don't where never going to pay anyway. They aren't losing money.
