How to download an MP3 track from a YouTube video
There are several Q&A threads that explain how to download youtube videos using the terminal.
However, I would also like to learn how to extract the video's soundtracks as MP3 files--also using only the terminal.
Answers briefly explaining how to use youtube-dl
or other similar utilities before explaining how to extract the MP3 would be ideal for the sake of having all the information in one place--even though this aspect has been covered in other posts.

It's close but I think the fact that it is specifically looking for an mp3 makes it different enough.

In most cases you can download m4a or webm without conversion. This is an interactive script that will let you choose a specific 'rendition' such as audio-only, video-only, etc:youtube-dl -F "$1" ; read -p "Please enter the desired quality # " FORMAT ; youtube-dl -f $FORMAT "$1"

I'm voting to reopen this question because the linked question is quite different, doesn't have any answers and goes into a chain of duplicate questions that don't address audio extraction of Youtube videos.

You can also download the mp3 directly from youtube without converting using ffmpeg
youtube-dl --extract-audio --audio-format mp3 <video URL>
From the online help:
-x, --extract-audio convert video files to audio-only files (requires
ffmpeg or avconv and ffprobe or avprobe)
Bear in mind as well that youtube-dl defaults to using avconv so you should consider specifying either avconv or FFmpeg at the commandline . From the online help :
--prefer-avconv Prefer avconv over ffmpeg for running the
postprocessors (default)
--prefer-ffmpeg Prefer ffmpeg over avconv for running the
postprocessors
Further options for keeping the original video, adjusting the bitrate or quality of the audio and a few others can be seen by looking at youtube-dl -h
.

sudo apt-get install ffmpeg
Next have a look to make sure the flv file has downloaded from youtube by typing
ls *flv
This will list all the flv files you have. What you should see is a flv file with the same name as the 'v' component of the youtube url you downloaded.
E.g if you downloaded http://www.youtube.com/watch?v=_z-hEyVQDRA
then you should have a file called _z-hEyVQDRA.flv
Next you need to copy that file name and then put it in an ffmpg command like
ffmpeg -i <file name>.flv -acodec libmp3lame <song name>.mp3
So for this example you would type
ffmpeg -i _z-hEyVQDRA.flv -acodec libmp3lame MasterOfPuppets.mp3
Once this has successfully completed you will now have the mp3 file you were after.
Note
- For cleanup you may want to type
rm _z-hEyVQDRA.flv
to get rid of the flv file that you no longer need. - Information from here
You may want to add converting to mp3 with ffmpeg or aconv.

Downloading from youTube
Install youtube-dl from the official repository in Ubuntu:
sudo apt-get install youtube-dl
or as official readme suggest using curl
or wget
. This will let you upgrade with sudo youtube-dl -U
To download a video execute the following:
youtube-dl <url>
E.g
youtube-dl http://www.youtube.com/watch?v=_z-hEyVQDRA
You can also specify other options
-b Best quality
-m Mobile version
-d High Definition
-g Don’t download, just show the url
-c Resume download of a video which was interrupted before
-w Don’t overwrite existing file
For complete list of switches execute man youtube-dl
in terminal.
Information from here
Converting to mp3
Now install ffmpeg from the official repo.
sudo apt-get install ffmpeg
Next have a look to make sure the flv file has downloaded from youtube by typing
ls *flv
This will list all the flv files you have. What you should see is a flv file with the same name as the 'v' component of the youtube url you downloaded.
E.g if you downloaded http://www.youtube.com/watch?v=_z-hEyVQDRA
then you should have a file called _z-hEyVQDRA.flv
Next you need to copy that file name and then put it in an ffmpg command like
ffmpeg -i <file name>.flv -acodec libmp3lame <song name>.mp3
So for this example you would type
ffmpeg -i _z-hEyVQDRA.flv -acodec libmp3lame MasterOfPuppets.mp3
Once this has successfully completed you will now have the mp3 file you were after.
Note
- For cleanup you may want to type
rm _z-hEyVQDRA.flv
to get rid of the flv file that you no longer need. - Information from here

You may want to add converting to mp3 with ffmpeg or aconv.

One more,-acodec liblamemp3
in the ffmpeg command line.

Yes you could force the codec to be sure, I have added this. You could also use-ac 2 -ab 128k
to ensure it converts at 128k

Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
Would you like to answer one of these unanswered questions instead?

It's close but I think the fact that it is specifically looking for an mp3 makes it different enough.

In most cases you can download m4a or webm without conversion. This is an interactive script that will let you choose a specific 'rendition' such as audio-only, video-only, etc:
youtube-dl -F "$1" ; read -p "Please enter the desired quality # " FORMAT ; youtube-dl -f $FORMAT "$1"

I'm voting to reopen this question because the linked question is quite different, doesn't have any answers and goes into a chain of duplicate questions that don't address audio extraction of Youtube videos.
