I personally used spotdl when I wanted to transfer my music off of Spotify. It does unfortunately only download from YouTube which means its not 100% successful, it missed a handful of songs for me and 1 or 2 had an incorrect version altogether (like 10 hour loops, etc.). Overall it was like more than 99% correct for my playlist of around 2000 songs though, and its super easy to use especially in either a python or shell script since its a python library with a cli built in. There are definitely other options I don’t know about, some of which are probably better tbh, but spotdl has been good enough for me personally at least.
