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.
