/*
HOW TO USE (Chrome):
1. Go to Google Play Music
2. Once loaded, right click anywhere in the page and left click on "Inspect" (or press CTRL + SHIFT + I)
3. Go to the "Console" tab.
4. There's a little dropdown, select "top".
5. Paste this script next to the ">" and press enter.
6. You can now close the console. (Click the X at the right or press CTRL + SHIFT + I).
7. Go to the playlist you want to export.
8. Press 0 to start the export process.
   If pressing 0 does nothing, reload the page and make sure you you inject the code on "top" (step #4).
9. Follow on-screen instructions.
10. Once it's done, a file containing your playlist will download, paste it here:
   https://labs.villoslada.me/unportify.

NOTE: If the number of catched songs is lower than the number of songs in your playlist,
      you might have duplicates, if not, try lowering the scroll speed.

The script works correctly and catches the right number of songs, but whenever I attempt to import the data I get the error "Wrong Format".

Github won't let me attach the text file for some reason, but you can view it at https://pastebin.com/aaJG3yfx.

Any thoughts on this one?

@rwagner00 There's some format problems with the file that's generated by this script, to fix this, copy it from a source that removes the formatting, like pastebin. When copying from there, I was able to import your playlist: https://open.spotify.com/user/arnauvp/playlist/4AHDzaX2OookmrmGb1EZEl

Tracks that were not found: https://pastebin.com/qYy8HLdP

Unfortunately I cannot keep updating this script since my Google Play Music subscription has expired (I'm using Spotify). Any edits to the script are welcome!

@TheDegree0
"location" of the playlist title seems to has changed.
var playlist_title = document.querySelector('[slot="title"]').textContent;
That's working for me, thought I'd let you know

This is fantastic - works perfectly. Bravo!

@tadly Hey, thank you, updated the gist.
@ralphhogaboom I'm glad it helped!

Awesome script. I'm possibly migrating from Play Music to Spotify and just used the latest version to make an export.
Since I wanted to migrate everything I have using the songs tab I just changed line 145 a bit:

var playlist_title = "Songs"
if (document.querySelector('h2[slot="title"]') != null) {
    playlist_title = document.querySelector('h2[slot="title"]').textContent;
}

Just leaving this as note for anyone who wants to do the same :)

It worked flawlessly! Thanks man, you spared me a lot of time

Thanks for making this.

As @se-bastiaan pointed out it doesn't work on this link: https://play.google.com/music/listen?u=0#/all

For future reference this is the error:
TypeError: Cannot read property 'textContent' of null at scrollAction (<anonymous>:145:72) at pageScroll (<anonymous>:175:5) at c (https://play-music.gstatic.com/fe/5fe97bf3f03d8f910c21eadc88b3532e/listen.js:1169:261)

The fix by @se-bastiaan also works. Would you mind incorporating it into your script?

For some reason it does not work when I'm pressing "0" but calling

startExport({keyCode: 48})

in the console window works fine ;)

---

I don't know why but when pressing "0", it seems that no KeyboardEvent is passed to the startExport() method. When adding a console.log() to the startExport() method, I can see KeyboardEvents for other keys like "u". But "p" for example is opening the playlists menu in Google Music and does not output a log message. I think Google is grabbing and handling the "0" before Unportify can do.

Oh and by the way, MANY THANKS FOR YOUR EFFORT! ♥

Ctrl + 0 also works

@TheDegree0 thank you so much for putting this together, wanted to switch a few years ago but was dreading rebuilding some of these playlists.

@x3rAx thank you, that worked or me.

Thank you,

For some reason Ctrl + 0 worked but just pressing 0 didn't haha

Does it still work having some issues.
