Creators are often having to use royalty free music in their content. The reason being that using copyrighted music can lead to content strikes as well as demonetization. That issue has plagued user-generated streaming platforms for years. YouTube and Facebook both have continuously updated libraries of royalty-free content, but that hasn’t assuaged content creators who desperately want to play games along to their favorite jams. There has also been a history of YouTube taking down videos where creators are absent-mindedly (and often badly) singing bits and pieces of popular songs.
