It is very important to Clean you cache and block clients ad sites if you hear ad's then repeat the cleaning.
Lists there are 3 in use.
gsv8 19 domains
allhosts Updated most errors removed.
Linux snap installed: ~/snap/spotify/common/.cache/spotify/Storage
OS X: /Users/USERNAME/Library/Caches/com.spotify.client/Storage/
I have the list synced with a Nextcloud host so its easy to update.
I welcome any comments.
