These recommendations are good. I personally wrote my own Python script to use the Spotify API to get playlists and metadata then download the audio off YouTube.

It's similar to spotdl but the last time I used them, they were only taking the first audio (which could be the music video version). So for my script, I put a filter for duration, prioritize YouTube music, and use keywords like "lyrics" and "official audio" that's more likely to match the Spotify version

You can look into Spotify Downloader spotdl, a Python package here: https://github.com/spotDL/spotify-downloader

It doesn't download as you listen, but it'll do something smart and download all the tracks of a playlist/album/etc by grabbing high-quality audio from Youtube videos (and it magically avoids dreaded music video versions) if you feed it a Spotify URL. It also puts all the metadata in the tracks automatically.

Spytify worked last I checked, it pretty much just rips from the audio output stream so it's essentially impossible to block. On the downside without creating a dev api key the metadata is kind of iffy (it will attempt to grab it from somewhere other than spotify without the api key) and being a stream copy it can only copy as fast as they can play.

When I was in school for radio I was outputting the Spotify player to the rack then bringing it back to an input to record through audition.

Kind of tedious, but it worked.

Deemix is a good option. Will download Spotify playlists from Deezer.

Onthespot has download as you listen to feature but i never tried it so cant say how good it works
