How is it that people can post musical soundtracks and pop songs on YouTube? Doesn't that violate copyright laws?
Youtube has a service where copyright owners of music can monetize infringing videos such that ad revenue goes to the copyright holder rather than the uploader.
Alternatively the copyright holder can choose to have the video stripped of the music or taken down.
In all other cases, the copyright owner simply isnt bothered to employ people to find illegally uploaded copies of the music
