In this guide, I will show you how to convert a music video from youtube to mp3 file in a simple and fast way. The first thing you need to do is to install Youtube Multi Downloader which you can download from here.
Once we have launched the Youtube Video Downloader program that looks like this :
we go to youtube and select, copy the link to the music video that we want to convert to an mp3 file, then paste this link to the YouTube Multi Downloader program, I chose this music video.
link to this video : https://www.youtube.com/watch?v=l9CjoDkHLsc
then we choose the quality of the mp3 format, I chose the best quality, and then choose where the file is to be saved, I chose my desktop.
if you are ready to download, just click "Start Download", file will be downloaded and converted instantly :)
done... file downloaded and converted within 5 seconds :) great !
