I've been very impressed with Simfy thus far. The desktop app is solid, streaming works great, the Android app is good, offline playback works fine and the track selection is excellent. R60 a month for an instant 18 million track library, no need to store anything locally, as much offline access across your devices as you want, playlists that 'sync' instantly across your devices, social functionality and an amazing means of discovering new music is an absolute steal for R60. You could spend that amount on Amazon or iTunes every month for a hundred years and you wouldn't come close to 1% of that amount of music.
