MP3TAG OPTIMIZATION

1. Fix Audio Tag Name Case (_FIELDNAME)

Metadata field keys inside audio containers (such as FLAC or M4A) can often end up formatted in all uppercase (e.g., ARTIST, TITLE, ALBUM). Follow this procedure to standardize field keys themselves into clean Mixed Case (Title Case):

1. Load your music directory into Mp3tag and select all files (Ctrl + A).
2. Press Alt + Shift + 6 (or navigate to Actions > Actions).
3. Click the New (star) button to create a new Action Group and name it Fix Tag Key Case.
4. Click New inside the action group window and select Case conversion from the dropdown menu.
5. In the Field input box, manually type: _FIELDNAME
6. Set Case conversion to Mixed Case.
7. Click OK, ensure your new action group checkbox is enabled, and click OK to execute.

2. Remove "(Album Version)" from Titles & Filenames

Clean redundant metadata tags such as (Album Version) or [Remastered] from your Title fields, then automatically update the physical file names on disk.

Part A: Strip Unwanted Text from Title Tags

1. Select all tracks (Ctrl + A) and open the Actions panel (Alt + Shift + 6).
2. Create a new Action and select Replace from the dropdown list.
3. Set Field to: TITLE
4. Set Original to: (Album Version) (Note: Include the leading space before the parenthesis)
5. Leave Replace with completely blank.
6. Click OK and run the action group to sanitize your title tags.

Part B: Update Physical Filenames on Disk

Now that your metadata Title tags are clean, update your actual files on disk to reflect the changes:

1. Select your files and press Alt + 1 (or select Convert > Tag - Filename from the top menu).
2. Enter the standardized format string below:

$num(%track%,2) - %title%

Click OK to batch-rename all files on disk instantly.

3. Download Tags & Album Art from Apple Music

Fetch official, high-resolution album artwork (up to 3000x3000px) and master metadata directly from Apple Music using custom Web Source scripts.

Required Script File Types

The Apple Music Web Source package uses a modular structure consisting of 3 distinct file extensions. All 3 components must be extracted into your sources directory for the scripts to operate:

Note on Region Scripts (.src): The package includes multiple .src files corresponding to specific country store fronts and localized titles (e.g., &Apple Music#USA (English).src, &Apple Music#UK (English).src, &Apple Music#भारत (हिंदी).src). You can copy all region files or simply choose the ones relevant to your store preference.

1. Visit the updated Apple Music Web Source thread on the Mp3tag Community Forum →
2. Download the latest release zip archive (e.g., Apple Music for MP3Tag (Web) 3.21.zip).
3. Inside Mp3tag, navigate to Help > Open Configuration Directory.
4. Open the data\sources subfolder and extract your chosen regional .src files along with the core Apple Music Web.inc file into this folder.
5. Restart Mp3tag. Select your album tracks, then go to Tag Sources > Apple Music (or press Ctrl + I).
6. Search for your album title, match the returned online tracklist with your local files, and click Save to embed high-res cover art and master metadata tags directly into your files.
