Definitely not an isolated issue as channels from manny different backgrounds have had to deal with this.
Honestly the market is ripe for someone to come forward and offer creators a better deal than what YouTube has been offering. They seem very complacent.
It seems like there's a new breed of scammers who upload songs to YT or Spotify, then use them as basis of copyright claims. This can only happen because of how broken YT's automated system is.
