Why Plex Shows a Different Cover, and How to Keep Yours

You rip a CD, choose a clean scan of its cover, and see a different image when you open the album in Plex. The title is right. The tracks play. The artwork belongs to another edition, or simply is not the one you chose.

Before replacing anything, check where Plex is getting the picture. Its music settings allow artwork from matching, local files, or both. A cover stored in your tracks can be present and still lose the preference decision. Understanding that choice makes the repair more direct.

The collector's question has two parts: which image should Plex display, and where should your chosen image live? You can address the first in Plex's settings. Private Press can help with the second by pressing artwork into supported music files in a local folder or mounted NAS collection.

Check the artwork preference first

For libraries using Plex Music, Plex documents three Album Art options under the library's advanced settings: Plex Music Only, Local Files Only, and Both Plex Music and Local Files. The combined option is the default. It favors matched artwork unless Prefer local metadata is also enabled, which makes local artwork preferred. Plex's music metadata settings.

That gives you a practical first check. Open the music library's edit window in Plex Web and inspect Advanced. If Album Art is set to Plex Music Only, pressing a new cover into your files will not by itself change the selected source. If you want artwork gathered exclusively from your files and nearby artwork images, choose Local Files Only.

The combined setting is useful when you want online artwork available alongside your own. Its preference behavior matters, though: enabling Prefer local metadata reaches beyond the cover image into how Plex uses your tags. Decide whether that broader choice fits your collection before switching it on.

These are documented behaviors of the Plex Music system. An older library using another agent or scanner may need different instructions. Check your library configuration before following a guide written for a different setup.

Local metadata asks you to maintain the tags

Prefer local metadata makes your embedded tags take priority over the regular matched information. Plex expects accurate track, album, artist, and, where appropriate, album artist tags throughout the music library. Its own guidance cautions against enabling the preference by default and notes the possible tradeoff with richer information from online sources. Plex's embedded metadata guidance.

That can be a good fit for a carefully maintained collection. It can also expose inconsistencies you previously left to matching. In a hypothetical compilation, one track tagged with the album artist “Various Artists” and another with a performer in that field deserve inspection before you give local tags priority.

Keep the decision specific. If your immediate goal is to control cover sources, the Album Art setting addresses that directly. If you also want Plex to rely on your own titles and credits, audit those tags before enabling Prefer local metadata. You can choose the level of responsibility you want to take.

Put your choice somewhere you can inspect

A Plex setting determines what the server reads. A file edit determines what your music files contain. Make both decisions deliberately.

Plex supports local album artwork beside the tracks, including a cover.jpg in the album folder. It documents several accepted filenames and image formats for its default Plex Music agent and scanner. This is a valid option if you already keep artwork as separate files. Plex's local artwork documentation.

Pressing artwork into a supported track gives you another useful copy of the choice: the image becomes part of that music file. Copying the track carries those artwork bytes with it. Whether a particular player displays them still depends on that player's format support and artwork rules.

Private Press scans folder collections, including mounted NAS volumes, and provides artwork repair for MP3, M4A, FLAC, and AIFF. You can inspect an album, find the cover appropriate to your edition, and press it into the files Plex reads. You can also review metadata when a cover mismatch reveals a broader identification problem.

Private Press works with files in folders on your Mac and mounted NAS volumes. It does not connect directly to your Plex server. You choose Plex’s artwork settings and refresh the library after a press. Private Press prepares the files, while Plex controls what appears.

Refresh a small selection and verify it

After changing artwork or relevant library settings, refresh the metadata for a test album and inspect the result. If you are upgrading an older music library to Plex’s newer metadata system, its upgrade guide says to refresh the artist first; an album refresh alone does not perform that upgrade. Plex’s music-library upgrade guide. Plex distinguishes scanning for added or removed media from refreshing the metadata of existing items. Its guidance calls for a refresh after changing metadata options or adding local artwork. Plex's scanning and refreshing guide.

Use an album whose files and desired cover you know. Confirm that Plex points to the same folder you edited. Check for a sidecar image that differs from the embedded cover. Then compare the displayed image with your choice. If it still differs, inspect the source setting and the album's match before changing the files again.

Once that small check works, apply the same approach to a larger selection. Your collection now has two deliberate choices: artwork stored with the music, and Plex configured to use the source you prefer. Private Press supplies the file repair; Plex supplies the display policy. You can check each independently when a cover changes.
