Batch Tag Renamer

Batch Tag Renamer is a desktop tool for tidying a music library on Linux: rename many audio
files from their tags, fill tags from file names, and clean up tag text in one pass.
A lightweight Linux alternative to TagScanner for batch renaming and tag editing of local music files.

Key Features:
- Rename from tags: build file names from %artist%, %album%, %title%, %track%, %disc%, %year%,
%genre%, %albumartist% and %filename% placeholders, with a live colour-coded preview, conflict
detection and a swap-safe two-phase rename that is rolled back if anything fails.
- Filename to tags: parse names such as "03 - Artist - Title" into tag fields and write them to the files.
- Batch tag editing: set artist, album, year, genre and more on many files at once, apply Title Case /
lowercase / UPPERCASE / trim spaces to a field, and auto-number tracks in table order.
- Reads and writes real tags of MP3, FLAC, Ogg Vorbis, Opus and M4A/MP4 files through the mutagen library.
- Undo for the last renames and tag edits, CSV export of the library, bilingual (Vietnamese / English) donate bar.

Notes: works on files on your own disks only; it does not query any online tag database.
Hidden folders are skipped. Make a backup of irreplaceable files before bulk edits.
