They should absolutely fall under copyright. For song and music, this isn't that much of a problem. Pretty much every hit song that has ever been written is allowed to be uploaded in its original form at this point. It really is free promotion and they know it. What they crack down on is using music in your own videos, which really should only be allowed in pretty specific incidents without permission.
Television and movies are on their own playing field in this regard. While music uploads promote artists, television and movie uploads do not promote sales. They are far more expensive than music, so people are far less willing to go spend a good chunk of money on a DVD or a boxset when the entire film or series they're looking for is already online.
However, there is also the problem with content creation. There are lot of people that make their livelihood through content creation, so when someone copies that and uploads it as their own work, the owner should have every right to crack right down on that person.
