Because that is not Canadian Metal four piece Tomb Mold. (They’re pretty dorky looking too, it turns out, but that ain’t them.)
I think I know why it’s doing this: because my music library is organized under directories for each letter of the alphabet (/albums/T/Tomb Mold/…)
The same picture of eight Asian guys shows up for Talking Heads, too, for example. I’m just wondering if there’s a way to specify a better placeholder image. I’m perfectly happy to go digging in the server’s directories if that’s what it takes.
I noticed that when you’re on a page of a band with a background picture, it takes the background from that band when you open the play queue. Could that be what happened?
I doubt it because I have absolutely no idea who those eight guys are - they aren’t a band I listen to. The image for J bands is some hair rocker, and for D bands it’s some (presumably) K-Pop act, none of whom are in my library.
Not that this helps you, but I think it’s an image of T-Square. So probably Jellyfin treating your T folder as one whole artist.
