The Raspbian OS contains the standard distribution to play .wav files. However, if you want to play MP3 files, install the mpg321 library by executing the following command in the terminal:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install mpg321

You can play MP3 files with the following command:

mpg321 "my file.mp3"

Remove boot messages

Go to the Raspberry Pi terminal and enter the following command:

cd /boot/
sudo nano cmdline.txt

At the end of the file, add this:

loglevel=0 

The preceding line would suppress every log from the kernel. Reboot the Raspberry Pi, still you will see some messages. To remove these messages, use the following code:

cd /boot/
sudo nano cmdline.txt

Change console...
