Is it time to get MP3?
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.

Software needed to play and turn 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.
