我刚刚看到一篇名为“史上最伟大的 500 首歌曲”的文章，心想“哦，这太酷了，我打赌他们还制作了一个我可以关注的 Spotify/Apple 音乐列表”。嗯...他们没有。 简而言之，我想知道是否可以 1) 废弃网站来提取歌曲，2) 然后进行某种批量上传到 Spotify 来创建列表。
网站中歌曲的标题和作者的结构如下：
网站截图。我已经尝试使用谷歌表格中的 importxml() 公式来废弃网络，但没有成功。 我知道报废部分比其他部分更容易，并且由于我是编程新手，我很乐意设法部分实现这一目标。我确信这个任务可以在 python 上轻松完成。
，以及底部的 .txt 文件的输出路径。一旦完成并且您拥有 .txt 文件，您可以将其关闭。

cd进入文件夹并运行

找到var scope此处
现在返回var client_id 和 var client_secret

var redirect_uri将会是http://localhost:8888/callback

node app.js运行app.js（这基本上是在您的PC上运行的服务器）
现在，如果有效，请让它运行并转到 user_idauth
变量以及output_songs.txt
的路径（at with open）并运行，未找到的歌曲将在最后打印出来，用 Google 搜索一下。它们通常也在 Spotify 上出现，但谷歌似乎有更好的搜索算法（惊讶的皮卡丘脸）。

如果您遇到问题，也可以在Web API 快速入门
中或在Web API 文档中描述从第 2 步开始的所有内容。 关于Apple Music
所以苹果看起来非常封闭（惊讶哈哈）。但我发现你可以查询 i-Tunes 商店。给出的回复还包含 Apple Music 上歌曲的直接链接。 你也许可以从那里开始。
从 iTunes 搜索 API（Apple 音乐）获取 ISRC 代码
