The combination of 5G, AI, IoT and big data were evangelised at MWC as generating massive scope for the transformation of multiple industries.

Recorded music revenues in Japan are stuck in decline as physical sales sag, although 2017 marks the first year when streaming gained a foothold with 8 million subscribers. 

J-pop fans spend on 'experiences' with their idols including events, merchandise, CDs and DVDs, which streaming cannot replicate. Top native LINE MUSIC offers integration with a popular messaging app and bundling with mobile.
