Amit started downloading music when he was 16 years old in India.

"In a place like Japan, where virtually everyone has access to the Internet, it is easy to sell music over the Internet," Amit says. "People here don't mind; they're used to paying for stuff. I'm not."

Throughout the decade, Amit has downloaded hundreds and thousands of files containing movies, Western music, J-pop and Indian tunes. All of them were available at the click of a mouse via peer-to-peer file-sharing networks such as eDonkey, LimeWire and BitTorrent.
