export_google_music.js

// go to: https://play.google.com/music/listen#/all
// and paste this into a Chrome developer console
// A JS object will then be pasted into the clipboard containing all songs in the order they were listed
//
// After everything is processed, and you would like the output in a friendlier text
// format, you can call the songsToText() function. You can select a style and choose if
// only liked/thumbed up songs should be exported.
// The resulting list will then be pasted into the clipboard.

Getting the following error. How do I fix?

listen.js:1181 Uncaught gx {message: “Error in protected function: copy is not defined”, Osb: true, cause: ReferenceError: copy is not defined

Thank you a lot! You made my day!

Try https://musconv.com/ for export of the Google Music across many music platforms.

Actually don't this company spams the world with single-use throw away accounts to push their paid service.

Thanks so much for the script!!! It best solution!!!

Maybe you can replace allsongs[i].{spmething} on some like that:

getSongAttribute(i,'artist')

var getSongAttribute = function(index, attribute) {
  return allsongs[index][attribute].replace('\n','').replace('\r','').trim()
}

Because now there are escape characters and it brokes csv.

Thank you very much!
