I know that I’ve repeated myself a 100 times, and the Ninjas and Devs have probably placed me on the ignore list. For Plex to re-scan the entire library and try to match the “UnMatched” albums each and every time new media is added is ridiculous, even when the new addition is available at MB, tagged with and matched with Picard (the official MusicBrainz tagging software)
The scanning for unmatched albums should occur during the regular maintenance schedule, not every time anything is added or changed within the library. TV and movie libraries do not scan the entire library, only the affected folders, so why is a music library excluded from this normal and expected behaviour?
The albums are matched with the GUID of “local” if not available at MB. They display properly, with all of the correct info for title, track, genre, artist etc from the embedded tags. They are instantly available and playable when they are added. But Plex keeps on scanning the library trying to match the albums that have been there forever.
Adding an album to MusicBrainz can be a lengthy process, particularly for compilation albums. Each track (recording) has to be associated with an existing MB track ID, each track artist has to be associated with an existing MB artist, each release associated with an existing MB release group, etc. Then, you have to wait for the new addition to be available with Plex, (at least a day, at best) not to mention the 7-day waiting period that could happen if MB doesn’t approve the new addition automatically.
And all I wanted to do was have my old compilation CD scanned and added to Plex.
