python 自动将歌曲按照歌手分类创建软链接

要使用Python获取MP3文件的信息，可以使用pymediainfo包。
首先，你需要安装pymediainfo。

下面是获取一首歌曲信息的例子

"""
Module to demonstrate how to use `pymediainfo` to read metadata from a media file.

In this module, we read the metadata of a given MP3 file and display the artist's name and
other general information.

In order to use this module, you need to have `pymediainfo` installed.
"""


def read_mp3_metadata(base_dir, mp3_file):
    """
    Reads metadata of the given MP3 file.

    Args:
        base_dir (str): The base directory where the MP3 file is located.
        mp3_file (str): The name of the MP3 file.

    Returns:
        None
    """

    # Join the base directory and the file name to form the full path.
    mp3_file_path = os.path.join(base_dir, mp3_file)

    # Parse the media file using `pymediainfo`.
    media_info = MediaInfo.parse(mp3_file_path)

    # Print the artist's name.
    performer = media_info.tracks[0].to_data()['performer']
    print(f"Artist: {performer}")

    # Print the metadata of each track.
    for track in media_info.tracks:
         if track.track_type == "Audio":
            print(f"{'-' * 20} Audio Track {'-' * 20}")
            for key, value in track.to_data().items():
                print(f"{key}: {value}")
        if track.track_type == "General":
            for key, value in track.to_data().items():
              print(f"{key}: {value}")


# Example usage of the function.
read_mp3_metadata(r'C:\Users\user\Desktop\LX-Music', '2002年的第一场雪 - 刀郎.mp3')

注意， 简单的解析歌曲之后，基本信息在media_info.tracks[0]里面， 其实是 track.track_type == "General"里面
所以对歌曲分类的思路就是：
遍历指定目录的歌曲
获取每首歌曲的信息，这里指的是歌手的名字
同一个歌手的放一起
对同一个歌手创建文件夹，并将其对应个歌曲创建软链接放进去
