The package is working for me. Thanks for the quick update.

Adding the feedback.

@kparal, you were right. I was setting up a wrong configuration in my zsh shell. I can figure out the problem. Thanks a lot. After doing that I've tested general things on the package and it's seems to work properly for me.

I've tested the package using bash terminal and I can download audio from videos, but when I'm using zsh I can't. Tthe terminal output says: zsh: no matches found: https://www.youtube.com/videolink

If there is something wrong with the package using zsh shell?

The actual command that I'm using is: youtube-dl --extract-audio --format-audio mp3 https://www.youtube.com/videolink

Works in general purpose. =)
