Description:

Puddletag is an audio tag editor.

Unlike most taggers, it uses a spreadsheet-like layout so that all the
tags you want to edit by hand are visible and easily editable.

The usual tag editor features are supported like extracting tag
information from filenames, renaming files based on their tags by
using patterns (that you define, not crappy, uneditable ones).

Then there're Functions, which can do things like replace text, trim,
change the case of tags, etc. Actions can automate repetitive
tasks. You can import your QuodLibet library, lookup tags using
MusicBrainz, FreeDB or Amazon (though it's only good for cover art)
and more.

Supported formats: ID3v1, ID3v2 (mp3), MP4 (mp4, m4a, etc.),
VorbisComments (ogg, flac), Musepack (mpc), Monkey's Audio (.ape) and
WavPack (wv).
