The difference is in the amount and type of compression, which affects the size of the files and sound quality. An audio CD contains music in WAV format. Music that is in MP3 format is more compressed (smaller files), and takes up less space. An audio CD can normally fit a maximum of 16-20 songs in the normal WAV format (which will play in a normal CD player), whereas if the songs are in MP3 format you could fit hundreds of songs, but you would only be able to listen to the CD if the CD player is designed to play MP3s. The sound quality of MP3s is technically inferior, but the difference is indistinquishable to the average untrained ears. MP3's are common on the internet because the files are smaller, and therefore they can be downloaded and traded much more quickly.
