    Your computer has been playing music for years, one CD at a time. Now hundreds of songs can be
stored in your PC if they' re in the MP3 format (格式).
     What is it?
    MP3 compressed(压缩) music into small computer files. You may download MP3 music
several ways: Music can be downloaded from websites that have turned wide music libraries
into MP3. Once MP3 music is on your PC's hard drive, you can play it through your computer's
speakers, "burn" it onto blank CDs or swap(交换) MP3 files with friends using e -mail.
     How much?
     Software needed to play and convert MP3 music is often free. Compact portable MP3 players
start at around $ 40 and can hold hundreds of songs. A blank CD on which you can record music
costs about a dollar.
     Advantages  
    MP3 turns your home PC into a jukebox(自动唱机) . Small MP3 players are the size of a deck
of cards(一副牌), making it easy to take hundreds of songs with you.  
    Disadvantages

let you download music but can't be copied to MP3 players. And a growing number of new CDs
