whats the default background pic for music ?

im using dharma 2 (beta 2) with ellipsis 1.2. All up-to-date with apt-upgrade etc...
for some reason, I've imported all my music into my library, and all works fine.

...however!... the default background for music when playing it seems to have defaulted to my fanart for "The XX"

my library's stored on my servers MySQL db - dont know if this is the reason or if it's something more sinister

any help appreciated


ps it also shows this background in my album list for every single album

it appears that my "XX" fanart is the default background for the music section. weird
