The mobile app works only if you stay in the same place. It doesn't handle the latency changes you get while you're moving. On my daily 20 minutes commute I can't listen one song without having to force restart the playback while I have full 4G connection. Better download some music and listen it offline.
Doesn't work on Samsung S2 tablet. Hangs at splash screen. Doesn't seem to acknowledge orientation (no landscape mode).
