Next/Previous button on car stereo turns volume Down/Up on Android 4.3/4.4.2

Whenever I press the next/previous track button on my Alpine CDE 136BT head unit, my I9005 responds by turning android media volume down/up.
This happened in 4.3 aswell as 4.4.2. I have no idea why this happens so any helpful tip would go a long way.
