17kHz to 20kHz is missing.
I'm using Spek to analyze the audio file.

Using Audacity to record iTunes's sound. https://i.loli.net/2019/04/19/5cb8ab9e4b4eb.png Technically, a 235kbps AAC audio should contain frequencies up to 20kHz.
But using the DRM Removal, only 0 to 17kHz frequencies included.

Well, one could imagine that this is the spectrum where the DRM whatsit lurks. Spectrum removed, DRM whatsit gone.
