tracks are only available on Bilibili. You can easily find them using BV-codes - unique IDs for each video.

How It Works
Take any Bilibili video URL, for example:

https://www.bilibili.com/video/BV1E7CwYHEDN/
Replace the BV-code (the part after /video/) with the one you need

Simplified Option
I've already converted some favorite tracks to MP3 - download them directly:
🔗 https://drive.google.com/drive/folders/1m2zQG2W4yVdmtGcew9YNxmkwKxsfAEPN

To find another track - just change the BV-code in the URL, that's it!
