Will Spotify trigger a battle in the online music market? In 2007, Zing MP3, the first pay-online music site, officially opened the Vietnamese online music market. Zing MP3 is now the biggest online music website with 50 percent of market share. Nhan The Luan, CEO of nhaccuatui, said that that in Vietnam online music websites have to seek revenue from different sources. Meanwhile, hundreds of unlicensed online music websites still exist, challenging state management agencies and competing with authentic service providers.
