Song is not playable/downloadable due to server restriction.

[Linok-B]

Issue:
Certain songs have a warning before you try to reproduce them in youtube/youtube music, which usually warns the user that the song or video in question may contain inappropriate themes such as violence, self-harm, suicide, etc. Then asks whether the user would like to continue anyways or not. Pretty straightforward.
However, when trying to reproduce such songs via HarmonyMusic, errors "downloadError2" and "songNotPlayable" appear (The text message assigned to these errors is what actually appears).

To Reproduce
Try to reproduce any of the following:

• Lund - Broken
• Get scared - Sarcasm

Expected behavior
Being able to play the song, or download it for offline playing, without any issue. (Rather the second)

Personal info

• Device: RealMe C30
• OS: Android something (like 10 or idk)
• Currently residing in Spain
• No use of any VPN nor similar services

Note:
After looking at other similar issues here on github, I have noticed that most other users experiencing this errors are due to some songs being problematic in the US, especially by copyright issues (This is youtube's fault).
This is not the issue I am experiencing. This is due to me residing in Spain, and also experiencing these issues in one song in my personal Youtube channel (I made and published it, it has no copyright. Furthermore it is not the only song in my channel, and no other song exhibits these problems.)

Btw, I am really curious as to what exactly is causing the issue. Like, what exact part of the code.
