MP3, which stands for "MPEG 1 layer 3", is a highly efficient procedure for compressing digitally stored music and is the Internet-used standard. The MP3 player is a small portable device for playing back music files, which have been saved in the MP3 and other supported formats. Music from normal CDs can be converted into the MP3 format. MP3 data reduction will increase your music storage capacity more than ten times. Because of this, MP3 Players can be extremely small and most of them have no moving parts, which makes them perfect for listening music while sporting, or on the road.
