Create a Python script to batch-tag MP3s

Here’s a Python script that allows you to batch tag MP3 files using the eyed3 library. This script can update metadata like title, artist, album, genre, and year for all MP3 files in a directory.

Requirements

• Python 3.x

• eyed3 library (pip install eyed3)

Script: batch_tag_mp3s.py

python
CopyEdit
import os
import eyed3

def batch_tag_mp3s(directory, artist=None, album=None, genre=None, year=None):
    if not os.path.exists(directory):
        print(f"Directory not found: {directory}")
        return

    mp3_files = [f for f in os.listdir(directory) if f.lower().endswith('.mp3')]

    if not mp3_files:
        print("No MP3 files found in the directory.")
        return

    for filename in mp3_files:
        filepath = os.path.join(directory, filename)
        audiofile = eyed3.load(filepath)
        if audiofile is None:
            print(f"Could not load file: {filename}")
            continue

        if audiofile.tag is None:
            audiofile.initTag()

        title = os.path.splitext(filename)[0]

        audiofile.tag.title = title
        if artist:
            audiofile.tag.artist = artist
        if album:
            audiofile.tag.album = album
        if genre:
            audiofile.tag.genre = genre
        if year:
            audiofile.tag.recording_date = eyed3.core.Date(year)

        audiofile.tag.save()
        print(f"Tagged: {filename}")

if __name__ == "__main__":
    import argparse

    parser = argparse.ArgumentParser(description="Batch tag MP3 files in a directory.")
    parser.add_argument("directory", help="Directory containing MP3 files")
    parser.add_argument("--artist", help="Artist name")
    parser.add_argument("--album", help="Album name")
    parser.add_argument("--genre", help="Genre")
    parser.add_argument("--year", type=int, help="Year")

    args = parser.parse_args()

    batch_tag_mp3s(
        directory=args.directory,
        artist=args.artist,
        album=args.album,
        genre=args.genre,
        year=args.year
    )

How to Use

bash
CopyEdit
python batch_tag_mp3s.py /path/to/mp3s --artist "Artist Name" --album "Album Name" --genre "Rock" --year 2023

• It sets the title based on the filename by default.

• Add or omit metadata arguments as needed.

Let me know if you want to extend it to read tags from a CSV file or rename files based on tags.
