Howto set-up MOC (music on console)

MOC (music on console) is a console audio player for Linux/Unix designed to be powerful and easy to use. This guide details how to install and set-up MOC under Debian “Squeeze”/CrunchBang “Statler”. It also details how to scrobble tracks to Libre.fm.

Installation

MOC is available from the Debian repositories, it can be installed with the following command:

sudo apt-get update && sudo apt-get install moc moc-ffmpeg-plugin

Once installed, MOC can be run using the command:

mocp

The MOC binary is named ‘mocp’ to avoid a naming conflict with existing software.

Basic usage

Once MOC is running, the following keys can be used to control it:

           tab: toggle between directory list and playlist
             a: add selected track to playlist
             C: clear the playlist
         enter: play or move between directories
up/down arrows: navigation
             p: pause
             s: stop
             q: quit and keep running
             Q: quit for real
             .: volume up increments of 5
             ,: volume down increments of 5
             >: volume up increment of 1
             <: volume down increment of 1
             T: toggle to themes list, browse, and try them out

config file

Below is a config file for MOC, with sensible defaults. Copy the code below to the file ~/.moc/config.

Notes: If you have not previously run MOC, you will need to create the file. Also, the config refers to ‘monochrome_theme’, which is detailed further down the page. It also refers to the lastfmsubmit program, which is also detailed further down the page.

Scrobbling to Libre.fm

lastfmsubmitd is a submission daemon for the Last.fm social music network. It can be configured to work with Libre.fm as detailed. lastfmsubmitd is available from the Debian repositories and can be installed with the following command:

sudo apt-get update && sudo apt-get install lastfmsubmitd

During the installation you will be prompted for your Last.fm/Libre.fm username and password, you will also be prompted to enter a group name, leave the group name as ‘lastfm’. Once the installation is complete, add yourself to the ‘lastfm’ group with the following command:

sudo usermod -a -G lastfm $USER

Next, open the lastfmsubmitd configuration file:

sudo nano /etc/lastfmsubmitd.conf

Add the following lines, save and exit:

[server]
url = http://turtle.libre.fm

Next, restart lastfmsubmitd:

sudo /etc/init.d/lastfmsubmitd restart

Finally, you will need to log out of the user account and log back. Once you have done this, any tracks played in MOC should be scrobbled to Libre.fm.
