SEOUL— Samsung Electronics Co. said it will be shutting down its music-streaming service in the U.S. next month, just over two years after its launch, in the latest sign of the technology giant’s struggle to offer attractive apps. 

Samsung said on a notice posted on its website that it would discontinue the service as of Sept. 22. It didn’t provide a specific reason for ending the service and a company spokeswoman declined to elaborate.

Samsung said the service, which is powered by Slacker Radio in the U.S., would continue to be available in other markets including China, Malaysia and South Korea. The service was discontinued in Australia and New Zealand earlier this year.

Samsung’s Galaxy smartphones predominantly rely on Android apps, though over the years the company has moved to invest in its own apps to beef up its software offerings. But its efforts haven’t been very successful. Samsung launched its own mobile music and e-book service several years ago but was forced to shut them down after the services proved unpopular with consumers.

Samsung said in its statement that it would “invest and refine” its strategy to deliver better experiences to its Galaxy device users and said it plans to seek partners to offer improved music services. It recommended that its U.S. app users switch to Slacker Radio where they can also transfer their listening history.

Samsung did not disclose how many users will be affected by the discontinuation of the service in the U.S.

Samsung’s Milk Music service first launched in 2014 following the company’s 2012 acquisition of mSpot, a Palo Alto, California-based streaming music startup.
