music artwork missing
I just copied my Music library of 1.4tb from my iMac M1 running Ventura 13.4 to a hard drive. I then imported it to my older iMac running Monterey 12.6.6. All of the albums are now on the old iMac, but not all of the artwork shows up when I look at recently added. However, if I play a song in one of those albums without the artwork showing, the artwork shows up in the song. How can I get the artwork to show up when viewing the albums?
Do not say to click get album art as many of the albums are live shows that are not listed in the database, and I have tagged albums including the artwork myself. I know it is there, but just do not know why it does not show up in album view.
