Can MusicBrainz Picard handle a 9,000-CD music folder?
Yes, safely and at scale. Picard was designed for very large libraries (tens of thousands of tracks).
How Picard tagging works in layman's term, think of Picard as a smart librarian, not a player.
Picard does 3 things only:
- Reads the tags already inside your music files
- Matches them against the MusicBrainz database
- Writes standard tags back into the files
It does not:
- Play music
- Change file formats
- Delete anything
- Move files (unless you explicitly enable that)
Will Picard’s tags be read by Windows Media Player?
Yes, perfectly. Picard writes industry-standard tags that WMP understands.
