Ok, so I initially put an album art for Album A using the copy/paste method in Windows Media Player. This album art works everywhere, in every music app. By using MP3tag, I can see each track is tagged with this album art.
But now, I realize that I do not like the Album Art at all, and want to use an alternative album cover. I go to MP3tag, remove the album cover (and click save to be sure), and then I add the alternative album cover.
When I do this, and look at the album folder in File Explorer in Large Icons view mode, I can see that the new updated album art is displayed on each track.
However, there are some issues. On both Windows Media Player and Groove Music, the old album tag shows, not the new one. Also, in File Explorer, if I look at the album folder image, the old cover photo shows, not this new one.
Any way to "fix" this? Will gladly appreciate it!
