I am sure that many of you might have noticed that some videos on sites like Youtube are being removed or simply the audio is being removed due to copyright infringement. It seems that users cannot so easily just use any song they like for their video. Companies that hold rights for the song may want to be paid royalties for it, although that is not really possible since uploaders to sites like Youtube do not rally get paid. Since that is the case, we will just have to live with the fact that we might sometimes need to play our own music when watching some videos on sites like Youtube.
