Mog is a subscription music service that offers over 16 million songs at 320kbps.
Although its library may not be as comprehensive as JB Hi-Fi Now or Spotify, Mog is powerful, reliable, and consistent. In general, the app is extremely user friendly and operates smoothly. At the same time, though, music addicts (ie. users with enormous libraries) could face the occasional delay or bug.
While it does not matter which service provider your smartphone is connected to, Telstra customers benefit most from Mog due to a recent partnership between the two organisations. As a result of the agreement, Telstra customers using Mog do not consume any of their data allowance.
