I downloaded this app some months ago. Started using it, enjoyed the free features and downloaded some songs. Everything worked well. Not until today, when I opened the app, everything disappeared. My downloads were all gone. I was asked to restore my previous downloads. And, to restore the previous downloads, this is only done with Wi-Fi connection. This was so painful. Now, I'm installing it again. I would have to download all my songs again. If this happens again, I won't use the app.
