I looked you guys up and I found out I could download blocked or copyrighted videos through the 4k downloader. I personally tried a video and it didn't work, help me out?

I tried to use the 4k downloader to get this audio (mp3) extracted and it didn't work for me. If anyone could possibly get the audio file for me that'd be great!

If you download the audio please upload to the site called dbr.ee so I can listen to the audio! I appreciate anyone who helps me out!
