| Maybe album cover art is just less meaningful in the year 2021. I couldn't care less what the album art looks like when listening to music on Spotify or YouTube. What I do care about is a current "About" tab in Spotify, a WikiPedia page, or maybe a well-maintained webpage for/by the artist. Not meant to be an indictment of visual art of this type, just suggesting that perhaps the "vector" needs to shift elsewhere. Good example is the backgrounds created by Cryo Chamber for their YT postings: https://www.youtube.com/watch?v=SbKDlzQgIwc |
However, there are nonetheless lots of people like myself that primarily listen to albums, maintain their own digital libraries, and use streaming platforms as a glorified "trial" platform for new music. I find those who tend to listen to music like I do really care about high resolution album art (and by extension the quality and accuracy of track metadata).
Frankly, since both needs are so widely different, I'm not sure there's any one solution for both. Goodness knows Apple Music tries, but to OP's point, it's clearly not succeeding in this effort.
