The nightmarishly intertwining world of music licensing is a popular topic here, especially considering the past outlandish actions of various performance rights agencies. On top of this, there‘s the multitude of different licenses, each one applying specifically to certain formats or outlets. If it‘s streaming on Youtube, it needs x license and y license. If it‘s streaming at Spotify, it needs x license and z license. If it‘s a radio station simulcast at the station‘s website, license x, y and z are needed, along with license aa. And so on.
