Music Assistant’s “Update metadata” action replaces outdated information instead of only filling empty fields. Corrected biographies, descriptions, labels and release dates can therefore reach items that already have details in the library.
Personal files take priority over streaming services and online metadata sources. If a source cannot be reached, the update only fills gaps, protecting stored information from being overwritten while a music server is offline. Automatic refresh still fills missing fields; genres, artwork and links remain additive, and lyrics are unchanged.
