Only preview of music tracks can be downloaded (without logging in). After logging in to Yandex account VDH shows nothing during music playback.

Maybe you can do this, Ctrl+Shift+E and reload the page where there is no detection. Then save the file shown in the image.
Attach as .zip file here with your reply.

Music is streamed in octet-stream type, which is clearly seen in Network logging tab:

The site may be doing something that the extension doesn't find the information for detection. I could find out if you shared your
network activity here.

Here is my HAR file: music.yandex.ru_Archive [25-08-25 19-25-15]-.zip

I see the octet stream links from your file but the first link is starting from segment 8. Try going to the page again and make sure
the network is empty or click trash can icon if there is anything showing. Then reload the page and start the music.
After that save the HAR file once more.

Thanks, I was right about it not finding the information for detection. The streaming information is in a json url.
But that's not all and this is the bad part. It looks like they are using encryption for the media. See the screenshot below.
Two parts, transport is labelled as "encraw" which could be mean encrypted raw data ( I asked AI ) and a key.
This I'd say means downloading won't be possible from yandex music. Recording might work but I'm not going explain more on
that.

Thanks anyway! Just wanted to point out that problem exists.
