I've been a Jaikoz user for about 8 years now, but haven't used it in some time. I have some new DSD files that don't have metadata so I installed the latest version wondering if dsf was supported... I was pleasantly surprised that it was!
For some reason the artwork was wrong from discogs and I remembered not being able to multi-update artwork in the past... but then I was able to drag and drop the new artwork in and see it take effect for all songs. Great work!
