Most of the publicly available ones that rip streaming services to lossless fail spectral checks. They can rip high quality MP3s which they then transcode to flac but if you were to upload this somewhere like RED you’d get shit for it. Literally every one I’ve found has failed the spectral check thread on RED
This MAY not apply for Spotify as they don’t stream lossless to begin with
The people that can actually rip fully lossless files from deezer, apple music, qobuz, tidal, etc guard that info like crazy. The second the method gets public you better believe all those companies are patching it out. Plus it probably doesn’t hurt that being the one with the keys to the method gets you like infinite ratio
