And please try to better describe your issue as it’s not very clear.
If you do not enable the prefer track option Symfonium will apply the album art to the songs. Album art being the first found art on songs from the album.
my music is located in two folder: Music1 and Music2, on my phone. I have a lot of tracks that have album tag but don’t have any image, so all of the tracks borrow the image track from a random track with image and with album tag. tracks with no album tag don’t have image (as expected), only tracks WITH album tag (and no image embedded) some why borrow the album image from a different track.
I tried uploading the log, so pls check
If the songs are from the same album then as said, they will take the image from the album that’s normal and expected so that people do not have to put images in all the tracks.
Both your folders have a folder.jpg image, so that’s the image that is used for an album when there’s no embed image as expected. If that’s the image used then remove them.
