I loved this app until it deleted all music from my iPhone while playing songs on shuffle. The current song suddenly stopped and then my library was completely empty. All songs gone. Playlists were there but empty.
Luckily I have everything on my computer but I still lost all new playlists I had created.
I wrote to Support but never got a response. Seems like a serious bug to me.
