I definitely was not aware Spotify DRM had been cracked to enable downloading at scale like this.
The thing is, this doesn't even seem particularly useful for average consumers/listeners, since Spotify itself is so convenient, and trying to locate individual tracks in massive torrent files of presumably 10,000's of tracks each sounds horrible.
But this does seem like it will be a godsend for researchers working on things like music classification and generation. The only thing is, you can't really publicly admit exactly what dataset you trained/tested on...?
Definitely wondering if this was in response to desire from AI researchers/companies who wanted this stuff. Or if the major record labels already license their entire catalogs for training purposes cheaply enough, so this really is just solely intended as a preservation effort?
