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
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
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
For those with traditional music files (MP3, OGG etc.), the file format for exporting playlists is called "M3U8”.
It is literally a text file where each line is a file path.
Those are also a good thing to find in a page source to use with yt-dlp if you want to rip a video from a page, it’s like the playlist for DASH so you download all the pieces of a video and it’s audio and they get put together as one thing instead of getting little silent 5s videos that you have download one by one and also find the audio for them separately.
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
