Here's my #hiddengems for you guys in North America. Since this app launched in Indonesia, it has directly competed with Spotify for providing free offline streaming on any songs, even Indonesian songs. No subscriptions are necessary needed as they use the coins system as the way to provide legally copyrighted music in a jukebox way. I'm finding this app interested because you can actually play copyrighted music, all without internet connectivity, which means you can avoid paying for monthly subscriptions just to hear your favorite tracks while on planes or boats.
