One of the biggest messaging apps in the world is testing a new streaming music service, and it only costs $2.

Too bad you don't live in Thailand.

Line, the Japan-based messaging app that claims more than 205 million users, launched Line Music on Thursday (May 21). The service starts out free for current Line users ad bumps up to $2 after a month of use. Line hasn't revealed how much music is currently available on the service.

Line Music taps Line's messaging capability, giving users the ability to seamlessly share tracks with friends over chat.

Curiously, Line also owns MixRadio, the playlist app that launched on Android and iOS this week. Line hasn't said whether Line Music will expand out of Thailand -- let alone to the U.S. -- and they did confirm to TechCrunch that the two services are being run independently of each other.

But a streaming app that incorporates messaging capabilities in an innovative way would be a unique offering on the increasingly-saturated streaming service market.
