Spotify's founder, 29-year-old Daniel Ek, created the enormously popular music streaming service because he wanted to beat piracy issues.

"I was born in Sweden, and in Sweden we are known for the piracy services," Ek told ABC News' John Muller in an ABC News / Yahoo! News Newsmakers interview." I decided I wanted to create a product that was better than piracy."
