Our app submission was recently disapproved for Amazon Underground, and the reason given was "App contains music streaming/download ability". The app - Ultimate Driving Mode - is an app to provide access to hands-free calling, texting, music/media player control, navigation, and Amazon's Alexa while in the car.
The app does not directly stream music. Instead it controls other apps on the phone that do. For example, the user can use a voice command to tell Google Play Music to play a song by a favorite artist. While music is playing, the user can use a swipe gesture to advance to the next song.
The music player control is only one feature of the app among many. Music playback not the primary purpose of the app.
It seems like the app would be a good fit for Amazon's ecosystem, since it provides access to Alexa. It cannot stream music through Alexa, since Amazon currently blocks this.
In looking at the app store, I found at least 2 music player apps that have been approved for Underground:
These apps directly play music. Our app only controls other players that do.
Can someone from Amazon provide more details on the reason for Ultimate Driving Mode's disapproval and provide suggestions on how the app could be modified so that it is approved?
