I’m not trying to be an ass but if someone who owns the song sends RU-vid a request to take it down they just legally have to. Often times it’s not even that though many channels who post these Juice WRLD songs monetize their channels and if RU-vid finds that they are using some else’s work to profit they don’t let them monetize so to subvert this the channel owner will take it down themselves so they can continue profiting off a dead man’s back.
