The streaming platform — similar to Spotify — currently operates in the Solomon Islands and Tonga.
It exclusively caters to listeners in the Pacific Islands, with over 350 artists from the region as well.
These artists are able to not only promote their music on mJams, but also receive royalties from listeners streaming their music.
In Papua New Guinea, mJams will be the first online music streaming service in the country.
As part of the new venture in Papua New Guinea, mJams has partnered with PNG Central Music Association to also bring the country’s archived music to a digital platform.
“A lot of their music is still on cassettes,” business development manager Aaron Egan said.
“We’ve got basic machines to convert cassettes to MP3, and download all the album artworks and extra information.
“It allows newer artists to listen and make mixes.”
Mr Egan said the expansion to Papua New Guinea was part of a progressive plan to become a streaming service for the entirety of the Pacific Islands.
“The entirety of the Pacific is the plan from us and we’re not far from it,” he said.
