Usually it's the other way around. A well made video can make a mediocre song better than it is. But one time a video kinda ruined a song for me for a bit:
This was a good slow jam when it came out, catchy as fukk. Then I saw the video and it was just too weird. Even for Michael. He looked extra strange in that video. Flaunting his bleached bird chest, half naked with Elvis's daughter. Whenever I would hear the song after that it would remind me of that weird imagery.
