Automation of Downloading YouTube Videos using VLC

[JMH2198]

Hello all! I am trying to download a bunch YouTube videos, and turn them into .mp3 files. I have decided to use VLC on a Windows 10 computer to do all this using the following processes:
1.) Open Network Stream in VLC and insert the YouTube Video link.
2.) Navigate to tools > codec information and copy the link in the "location" field.
3.) Insert the link from the "location" field into my web browser, and download the video using the options on that web page.
4.) Finally, I convert the downloaded video into the .mp3 file using VLC and move it into a specific folder.
As you may be able to tell, this can grow quite tiresome after a while. I am looking to create a program where I can insert the YouTube link, and it will go through all of those steps.
How should I go about this?
