Automatically converting the type is problematic, because if we change
the type of an option later (imagine str -> list), it'll pass the old
value to the new type constructor before any upgrade hooks are run.
With 6ff1f53, there shouldn't be any need to convert the types anyway
because sip now does that for us.
The 'convert' functionality has been repurposed here for actual format
conversions. As it happens, the only Option that needs that is the
password field (rot13).
MusicBrainz Picard
MusicBrainz Picard is a cross-platform (Linux/Mac OS X/Windows) application written in Python and is the official MusicBrainz tagger.
Picard supports the majority of audio file formats, is capable of using audio fingerprints (AcoustIDs), performing CD lookups and disc ID submissions, and it has excellent Unicode support. Additionally, there are several plugins available that extend Picard's features.
When tagging files, Picard uses an album-oriented approach. This approach allows it to utilize the MusicBrainz data as effectively as possible and correctly tag your music. For more information, see the illustrated quick start guide to tagging.
Picard is named after Captain Jean-Luc Picard from the TV series Star Trek: The Next Generation.
