NOTE: If you don't care about my story, jump to the bold text below and ignore the rest.
After using Google Play Music for a year, I started to miss some of Spotify's details.
On Google Music, you can be listening to calm, relaxing music, and get jump scared when the next song starts playing because the volume isn't equal for every song.
I also missed Spotify's humanized shuffle, where the shuffle feels random even though it isn't, or Spotify's artificial inteligence, that always recommended me amazing songs.
A year ago, I made the switch because no matter how many times Chromecast support was requested, Spotify wouldn't listen. That, together with a poor GNU/Linux client, made me dislike Spotify.
A year later, Spotify now has Chromecast support,
with a poor GNU/Linux client.
Because I miss some of Spotify's details and they, finally, listened to the community, it's time to come back, hopefully, to stay.
Now, the subject of this post says "[Release]" because I have a 931 song playlist on Google Music and I'm not transfering it manually, so I made a little script.
Tested on Chrome (02-01-2017).
Github \ (The instructions are in the script).

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.
