Zotify can download music directly from Spotify. You can bulk download or search individual songs, playlists, artists etc to download.

You need to have an account and a having premium allows you to get full quality downloads.

Zotify is great.

I downloaded approximately 3,000 songs in one go from a premium account to get the high quality versions.

Made me a little nervous but as the repo says, they have no reports of any one getting banned for using the tool.

Link for those interested: zotify.xyz.

It’s CLI based and has lots of options for bulk downloads or searching individual songs/albums/artists to download.
