Because - during the conversion from analogue to digital, the computer or recording device 'strips out' frequencies that are outside the human auditory range. We still here the tune, but are unaware that there has been some sounds removed. The digital tune still runs for the same length of time as the analogue version.

The mp3 extension of an mp3 file denotes that it is created using a different form of compression. If an audio file were not to have any compression whatsoever, the file size would be enormous. In a CD, compression is used to remove all of the unwanted and excess data, and the rest is high quality audio. In an mp3 audio file, the quality is compressed even further. This means that instead of being potentially 10's of MB large, it is only 1 or 2 MB. However, depending on how often it has been compressed, the sound quality may suffer for it, and you might experience glitches or artifacts in the sound playback.
