mpg321

mpg321 is a command-line mp3 player.

Why & when to use it?
* On old computers
* If your GUI stops working and you need some music while you are solving the problem
* Play music from your server
* Learn command line and practice it
* For fun

How to install it on Ubuntu?:
Open the Terminal (Applications → Accessories → Terminal) and type the following command:

sudo apt-get install mpg321

Key in Y and press Enter when you’re asked to install other required packages.

Example:

mpg321 -q filename

This code allows you to play a song without any details.

mpg321 -v filename

This code allows you to play a song with information of the file.

Of course it would be ridiculous to play music one by one file so we have to create playlists:

Open the Terminal (Applications → Accessories → Terminal) and type the following command:

(Find the location of your mp3 files by the command dir, cd, and cd...)
dir : Shows a list of all the files available in that directory
cd folder: Goes to folder directory (Replace folder with the name of a folder that you want to access)
cd.. Goes to previous directory

Example: Your music is located in /home/yourusername/Music so you should type cd /home/yourusername/Music

Then, create a playlist of all songs in this folder:

ls *.mp3 > playlist.txt

or create a playlist based on artist(Example abz)

ls | grep abz > abzplaylist.txt

*Tips: Replace abz with the artist name

To play the playlist:

mpg321 --list playlist.txt

Play it randomly:
*Little shuffle mode (Plays every file once in a random order)

mpg321 -z --list playlist.txt

*Big shuffle mode (Plays a random file and then plays another random file. mpg321 will go on until you stop it.)

mpg321 -Z *
