README.md

Usage

Once:

composer install

Everytime you want to rename mp3s:

php rename.php

composer.json

{
    "name": "mya/rename",
    "require": {
        "james-heinrich/getid3": "^1.9"
    },
    "authors": [
        {
            "name": "Mansour Yaacoubi",
            "email": "[email protected]"
        }
    ]
}

?>

Of course there is a lot of room for improvement.
