PhoenixPlayer looks super-promising, but there are a few things that are broken on Ubuntu Touch. One of them is that the default Music player is crashed hard when PhoenixPlayer starts up.
Current Behavior
Given Ubuntu Touch's default Music player is running and playing a music file
When I start PhoenixPlayer
Then the default Music player crashes hard.
Expected Behavior
Given Ubuntu Touch's default Music player is running and playing a music file
When I start PhoenixPlayer
Then the music in the default Music player continues to play.
Given both the default Music player and PhoenixPlayer are running
When one of the music players starts to play music
Then the other music player stops (or pauses) playing music.
