Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

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.

Spotify, like most legit streaming services, use Google Widevine DRM, and you don't reverse engineer it. At least not for the level that is required for this kind of content (L3). When you stream something in browser or device, the decryption module of that device is "talking" to the license server. If the identification goes through, the decryption keys are sent and the media gets played. So what you do is you extract that decryption module from a device, and then use scripts to send requests acting as that device, tricking the license server into sending you the decryption keys.

Once set up, and with the proper script, it can actually be even more efficient than other forms of piracy.

This is how they did the old one. Its a lot more complicated now, but the basics should be the same.

There was actually a project on github that claimed to allow downloading of Spotify straight from the source with drm bypassing called XSpotify but it was taken down by spotify before i got to try it: https://github.com/meik97/XSpotify

However it was archived on the wayback machine: https://web.archive.org/web/20200303145624/https://github.com/meik97/XSpotify

Obviously take this with a grain of salt, you should probably read the source code before attempting to run it
