I think it'd be great if we could set it on mobile that playback automatically resumes when we plug in our headphones or speakers or connect to Bluetooth, saving us from needing to open the Deezer App.
When you plug in something, it does nothing, but when you disconnect , Deezer stops playing. Also with calls it pauses and when call finishes, it plays again.
Plug in and play should be in settings and optional. My vote!
I think this is a basic feature and makes it easy to use the app while using the headphone plug-in without having to take out your phone while traveling or playing sports, for example.
