The default Rhythmbox music player that comes with Ubuntu 12.04 Precise Pangolin is pretty good, but some people need a higher level of performance out of their player software. Fortunately, it’s quite easy to install the Amarok music player in Ubuntu 12.04 Precise Pangolin. You need only go to a Terminal window and run this command:
sudo apt-get install amarok
(If you don’t know how to get to the Terminal window, you can get to it by clicking on Dash, searching for “terminal”, and clicking on the icon for Terminal. Alternatively, you can launch a Terminal window by hitting the CTRL+ALT+T key simultaneously.)
The apt utility will then install Amarok and all its dependencies. Amarok is designed to run in the KDE environment, and Ubuntu by default uses the Unity and GNOME environments. Amarok can still run in Ubuntu, but it needs to download a lot of KDE stuff first – about 220 megs worth. This might take some time.
Once apt has finished installing, you can run Amarok by going to the Dash, searching for “Amarok”, and clicking on the Amarok icon.
Note that Amarok requires a bunch of KDE desktop components running in the background, so if you’re on a system with limited resources, you might want to use a lighter media player.
