Always in relation to the movies placed on the social networks, it happens that one films something in a public space and the background music to that film is a popular melody for which someone else holds the copyrights.
What if this person intervenes to defend his rights?
In this case, we are looking at an obvious copyright infringement.
Even if we are in the presence of a derivative work, that is to say of a segment of film in the duration of which, we hear in the background, a well-known melody, this melody is not our property, and its author has the absolute right to ask us to erase the sound of the film on the segment of the film where the music in question is heard, or that we pay a certain amount of money for it. Most of the time, this is the first chosen solution.
