A good music track does not _need_ a video, but some videos definitely can enhance the music or are just amazing by themselves.

'Sabotage' by the Beastie Boys (Spike Jones), 'Hunter' by Bjork (Paul White), 'Praise You' by Fatboy Slim (also Spike Jones), ... er Billie Eilish 'When The Party's Over', Apex Twin's Windowlicker (Chris Cunningam). There are so many great music videos that are more than just the song.

Of course, some are just the artist singing in front of a greenscreen, and that's fine I suppose. Still, they are fundamentally different to an excellent music video.
