WMG are those fuckers who claim your videos if you use copyrighted music. And of course they ban your video in every country region and everything. if you are a beginner YouTuber you might get a mini heart attack when you see it on your videos.. Also they ban lyric videos,, cause,, yes..

Example:
me:hey did you see my Hamilton speedpaint?
friend: what speedpaint?

me: :checks my YouTube channel: damn WMG blocked the video because i used 36 seconds of "the Addams administration"
friend : whaa thats crazy
me : i know plus i used the cut rap version that isnt an "official" song anyway
