Line (or LINE), a Japan-originated chat app, has just launched a music streaming service, Line Music, beating both Apple and Spotify to regionalising their services for the country.

Unlimited subscriptions will cost ¥1,000 (around $8), with 20-hour access available for ¥500 ($4). It plans to have a 30-million-track catalogue by next year.

Being a pre-existing app focused on chatting, it comes as something of a boon to the recently launched music streaming arm of Line. Rather than attaching social elements later on, like the simplistic and inevitable tethering to Facebook of Spotify, it's easy to switch between listening to music and chatting in Line, making sharing a new track you've just discovered, or having a remote listening party with friends, quite easy indeed.

But streaming in Japan has not really taken off yet: mobile streaming subscriptions last year totalled just ¥5 million (around $40,600). Still, giant Japanese label Avex Trax launched their own music streaming solution, Awa, last month.

This is not the first Line offshoot, however: they also recently launched an Uber competitor called Line Pay. This is in keeping with the thinking of Line CEO Takeshi Idezawa (pictured above) to touch every corner of your phone, making the app invaluable for everyday life – the Google for the smartphone generation, perhaps.
