I have seen many episodes of The Kapil Sharma Show on Sony's YouTube channel and noticed that whenever a song comes, they just mute it and replace it with some generic music piece. But why? When the same episode comes on TV, they use the same song freely. Even in most of the time song is from the film which is promoted by the episode guest, then why it can't be used in YouTube? How does music usage rights work in YouTube and how it's different from television broadcast?
I have noticed it in few other shows too like Comedy Circus where they mute the entry song of the contestant.
