A、the recording industry and on- line record companies B、the recording industry and downloading - program operators C、EMI and on

The world’s No. 3 record company, EMI became the first major music company to sell a large selection of its recordings on line on Tuesday.
   It related more than 100 albums and 40 singles from acts of famous singers of various styles for fans to download from their computers.
   EMI’S downloading trial came as Legal battles rage over copyrights and digital music distribution between the re- cording industry and online music providers like MP3. com Inc.. MP3. com provides access to music via the popular MP3 technology, a compression format that turns music on compact discs into small computer fibres. EMI’ S music will be available in the future in secure format, after the company develops a player that supports the format.
   Current MP3 technology allows fans to copy songs again and again, the encoded software being used by EMI will limit consumers from hard drives. A consumer can turn the song to a CD twice and send it to a portable device three times.
