I want to use it but does it support subscriptions/ accounts? I have a lot of subs and I don’t wanna resub manually to all of them :(

EDIT: You absolutely can:

1. Go to https://takeout.google.com/ (login if needed)
2. Select only YouTube > All YouTube data > Deselect all > Select only Subs
3. Download the takeout file and extract the .csv
4. In Freetube, go to Settings > Data Settings > Import subs and click on the .csv
5. Enjoy!

Thanks for the info!

For sure. I prefer audio quality but this was easy to use.

I used spotdl to download mine. Though it grabs your music from YouTube, not from Spotify itself (downloads MP3s from YouTube) https://github.com/spotDL/spotify-downloader
