There are a few tools that can export your spotify playlists into folders of audio files. That's what I used a few years ago for my initial spotify -> navidrome migration.

But they're not that good. They look for the songs on youtube, and the versions uploaded there are often modified (or just very low quality). And I've had some issues with metadata. I'd say about 5% of my songs had some issues, and 1% were completely off.

Once they release the actual torrents and not just the metadata, I'm assuming that new playlist export tools will soon show up, and they'll use these new torrents as source instead of youtube. They'll be a lot more reliable. I'd wait for that to happen. In fact I may end up re-exporting my old spotify playlist.
