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
