I’m largely asking about between Spotify and Apple Music, but hell I’ll take suggestions for Youtube Music, Tidal, and Windows Media Player while I’m at it because that information will be useful to someone.
All my searches so far have proven fruitless, but FOSS seems to evade web searches unfortunately so if anyone knows of a community-grown tool I’d love to know
Also, soundiiz
A few years ago I used the Spotipy Python library to poke at Spotify’s API. I was able to scrape my playlists into CSVs with it.
If I cared more, I could probably hit up YouTube with those CSVs and try to make playlists on there out of them, but I never got that far lol
I used soundiiz, it costs $5 a month but i really just needed it the one month. I exported to a csv and then downloaded it all using tidal-dl and streamrip. You can import/export across a bunch of different serciservices.
Last time I used it (been a while though) it was free, if you only transferred playlists up to 200 songs
Tidal recommended this one when I moved from Spotify a few years ago. It worked, but I don’t know anything else about it: https://tidal.com/transfer-music
