Music was the first and the most common form of in-flight entertainment. In the early days of IFE, listening to music also had disadvantages such as single options and no visual interface. Envee, cooperating with several music portals in China, is able to provide music content for free or against a fee, including high-quality music, radio, podcasts and audio books, with the goal of providing a better service to his audience and improving passengers’ experience while flying.
