This is when you'd need a YouTube music downloader. The purpose is to convert a YouTube video to just audio, or, in other words, extract the audio from a YouTube video to make an MP3.
Below are several free ways for downloading YouTube music, some of which are online converters and downloaders while others require you to install software to get the MP3.
Note: The legality of these websites depend on the country you're trying to access them from. If you can't get to YouTube from your country, try a VPN service like Private Internet Access.
Contact me if you find something inaccurate or you know of any other awesome ways to download YouTube music.
Convert2MP3.net is an awesome website for downloading music from YouTube. You can search for videos to convert or enter the direct URL to the video you want the MP3 for.
Before you start the conversion, you can choose different audio formats like M4A, AAC, FLAC, OGG, or WMA. A few video formats are also available.
Click convert once you find the video you want (or enter the URL you want), then optionally edit the tags to add a title, album, and even cover image to the file. Choose Download to get the audio from the YouTube video.
A share button is also on the download page so you can share that specific conversion with others.
A bit like these other online converters, ListenToYouTube.com lets you convert YouTube videos to MP3 and then download the audio file for free.
Just enter the YouTube URL on the first page and then click GO to get started. Let the video prepare, and then you'll be told to choose the link called "CLICK HERE to get your Download Link". That's it!
Very much like the previous website, VidToMP3.com follows nearly identical steps to convert a YouTube video to an MP3 for music-only playback.
Enter the YouTube URL, click Download, and then wait for the conversion before seeing Click here to get your Download Link. Finally, click that link to see the Download MP3 button like what's in the image above.
Use VidToMP3.com if Video2MP3.net isn't working. They are completely different websites, but it appears as though they work in a very similar fashion.
