Mp3 music, all songs are created equal

Mp3 music is one of the most efficient ways to store and playback audio data. Whether commonly digitized music takes up lots of space (just take a look at an audio CD, with 700Mb just taking 80 minutes of audio), mp3 music uses a process called lossy compression to discard little bits of information, and greatly reduce the amount of storage needed.So, how does this process work? Just as you can't hear a whisper when someone is shouting in your ears, mp3 selectively removes parts of the music that you wouldn't hear anyway. That inaudible information takes a lot of space just the same. The resulting mp3 music file will be a lot smaller and  if done correctly  will sound just the same as the original.

Of course, if you increase compression to get an even smaller file, you'll probably start to notice the mp3 audio quality getting worse. But even so, if you consider audio quality/ file size ratio, mp3 music is unbeatable Thats the reason why you see so many mp3 players around you.
