First review: Sorta worked then started skipping, hopping from song to song. On Lenovo tab. Works well elsewhere so uninstall on the tab Second review: now it won't work at all with my mp3 files. In other words I'm screwed if I want to play any of the thousand songs I've ripped from my CDs over the years. I often am "off the grid" say hiking, sailing, flying, etc. and Amazn Music tortures those times.
