1) The music video for "Hey Brother" by Avicii uses and develops conventions of the genre more than challenging them. It follows typical narrative structures, settings, and camera techniques for a pop music video.
2) However, the central topic of domestic abuse does challenge conventions by focusing on a serious social issue rather than a typical romance.
3) While most elements conform to expectations, the narrative leaves the audience with an ambiguous resolution, allowing for different interpretations. This small challenge encourages reflection on the video's message.
