This person used copyright just fine I think. They are able to use his lyrics because they stated below the video: They do not own the video. All credit goes to the ones who created the song, which is Michael Buble and WMG, and they have nothing to do with them. They also state that they will not be redistributing the song. This disclaimer is very important. This person gave credit to the owners, and that is a correct way to use copyright. This person also used this video for educational purposes, and that is a proper use as well. What this person did wrong is that they do not give the source for the photo of Michael Buble posted at the beginning of the video.
This person used copyright well by stating underneath that there is no copyright infringement intended. They also used an acceptable amount of the episode. They do not, however, give credit to the website where they acquired the video.
