This means that if you want to show, say Transformers, you have to negotiate with one company to show the picture, another company to license the sound, and yet another company for each set of subtitles.
Sound is part of the film license in the US and Europe. This includes music and songs within the film. Studios pay out big bucks to license songs for films.
For example: my current employer would pay a license of approximately $500 to license major label music that will be played at an event to a live audience, broadcast globally, and streamed to 10 million viewers. (The total music budget for a 3-day event is maybe $5000, and that covers hours of music.) A movie studio licensing that same song for a movie would pay a minimum of $25,000, just for that song, assuming that it's part of the back catalog. A song that made the top 100 of the Billboard lists when it was released could command more than $100,000.
That's not entirely accurate. The song is only licensed for certain uses. For old TV shows especially, digital streaming wasn't a thing, so it wasn't included in the license. They have to be renegotiated for streaming.
That's why sometimes the songs in the shows on Netflix are different than the ones on the DVDs, for example.
