I think maybe part of this is that I hold my phone in my hand while listening.
So pressing pause on the Amazon Music app is second nature, especially as I do a lot of mobile listening using the app on my phone.
Subsequently, putting my phone (on which I’d usually pause) down to pick up a remote to do the same thing is counterintuitive.
But I appreciate others may have different habits. If you don’t listen on your phone a lot, and are used to a traditional CD player, or whatever, the remote is going to be pretty automatic, I suppose.
