I can confirm that this works quite well. I use these tactics all the time on my parents’ feed to keep them from watching too many “crap” news, pardon my french. There’s a very notorious news channel in our country that insists on feeding bad (and only the bad) news - I often remove their channel from the suggested feed play videos of funny fails/wins, cute cats, daily dose of internet and other happy nonesense.
Give us an update sometime @[email protected] , hope all goes well with your mom.
Pretty cool, but won’t your discover weekly playlists never update based on your new self hosted songs? I figure if you stop using Spotify, the lists it suggests will eventually tend to have the same songs/artists on repeat. It’s a very minor gripe seeing as how you can always just manually search and find new songs based on radios and such. Best of luck!
