I have a music library on a USB disc organized in a common fashion so that each album is contained in its own directory with a local file 'cover.jpg'. I would like these files to be the primary (ideally the only for local files) source of cover art so that they would be fetched according to the file path of the playing song - without, e.g., reference to the metadata.
Some of the files appear but most do not. This happens using both the Android App and a web browser.
All of the files are valid jpegs; in fact the whole library works as intended using Nightingale music player on the Mac.
