Dua orang inilah yang mengawal pengembangan format musik digital MP3 di Fraunhofer Institute, Erlangen, Jerman. MP3 memang menakjubkan. Ada banyak format untuk musik rekaman di Web, tapi MP3-lah sejauh ini yang paling populer -- dalam waktu yang sangat singkat. Salah satu perkiraan mutakhir menyebut jumlah musik berformat MP3 yang ditaruh di Internet mencapai setengah juta.

A child was crying. His father was trying to distract him to no avail. "I don't want to wear these torn out shoes. The child screamed inconsolably. "ALL my classmates wear new pair of shoes. they run like deer and laugh at pointing to my shoes." The child said innocently. The father was a poor man with limited means. He wanted his child to be happy and contended with whatever he had, but assured that he Will get a new pair of shoes the next month. when the child was adamant, the father told the boy that he would get them repaired. The child felt happy as he thought the cobbler wont repair his shoes as they were beyond repair.
