Unfortunately this flac is also kinda useless: AAC version has better quality. Spectrals: https://cdn.discordapp.com/attachments/852137485340377126/856606264531353610/2021-06-21_214515.png It's not the uploader's fault, some streaming platforms just lie about tracks' losslessness.

What is the source of the AAC version, if anything the peaks around the 21 to 22 kHz range look unnatural. Lossless vs lossy is not 100% defined by which has the higher peaks. What I'm talking about here is that the AAC has the same 20.5 kHz shelf as the FLAC version but then appears to spike. Next there is another shelf at around 21.75 kHz, with the occasional 22kHz spike. (This is usually a tell tale sign of an upscale).

Where did you purchase this? I'm trying to find a place that lets me buy the FLAC version.
