Moto X (2014) :: Music Keeps Playing During Phone Calls?

On my new Moto X (2014), when I'm listening to music via bluetooth (regardless of whether it's a headset or in the car), and I receive a call, the music keeps playing after I've answered the call, so I need to open the notifications tray and kill the music app (regardless of which it is). On my old Motorola phone, when I received a call while music was playing, it was pause the music. Is there any way I can make sure that answering phone calls pauses the music. It's kind of annoying to have my callers listening to whatever music I was listening to while I'm frantically trying to kill off the music app I had open.
