Show playlists a Google Play song is in

If you’ve got many songs in Google Play Music, it can be difficult to manage which songs are in which playlists. Google Play Music doesn’t show you a list of playlists a particular song is in, if any. To create such a list, here’s a solution that works.,output

The result will be a JSON file containing a list of songs where for each song there will be an array of playlists the song is in, e.g.

"Madonna - Santa Baby": [
"Madonna - True Blue": [],

In the excerpt above, we see that the song “Santa Baby” is in the Christmas playlist but the song “True Blue” is not in any playlist. You can then find a playlist to the the latter song in so you don’t forget that you have that song.
