I worked at SOCAN, the collective that manages the public performance of music. If I remember correctly, there are some licence fees that are paid by YouTube, but not necessarily for all of the user-generated content. These are experimental licences unless that has changed.
Right now, what we received as a decision from the European Parliament is that the statutes are voted on, and then each of the countries in the EU will have to make sure that they adjust their copyright acts so that all of these platforms have the obligation to pay licence fees. Even though the content is not theirs specifically, they have a responsibility as a broadcaster—I'm not using the right word—to make sure that they compensate the rights holders.
