XMMS is so far the fastest and easiest way to get your Mp3 tracks playing. It is available in the repositries of many Linux distributions like Ubuntu, thus very practical to install.
First update and control you’re repositories in sources.list /etc/apt/source.list then do
sudo gedit /etc/apt/sources.list To uncomment a line just take off the # sign at the beginning of that line. Save and close.
From the Terminal write down
sudo aptitude update
sudo apt-get install xmms
On xmms you can also import an equalizer for winamp files
