For people who are not willing to provide their credentials: I wrote https://github.com/tehforsch/striputary https://github.com/tehforsch/striputary which also records the music (meaning you need to wait for the entire length of the playlist for it to finish) and cuts it into songs. It doesn't require you to provide any credentials (and it should in principle work with other streaming services as well, but I haven't tried). It is probably not the smoothest user experience, given that nobody except me has ever used it, but I've successfully recorded thousands of albums with it so far.
