Other Picard Tasks
In addition to the general functionality of Picard tagging and organizing your audio files, there are some other tasks that it can perform:
Attaching disc ids to releases on MusicBrainz
This will read the id of a cd and attach it to a specified release in the MusicBrainz database. This will allow the release to be included in the list provided when someone uses the “Lookup CD” function.
Submitting track acoustic fingerprints
This will calculate the acoustic fingerprints for the selected tracks and submit them to the AcoustID database.
Generating tags from file names
This will extract tags such as track number and title from the file name.
Submitting cluster as a release
You can submit a cluster as a release to the MusicBrainz database. This functionality has long been available through a plugin, but has been included within Picard itself as of v2.7.
