Galaxy s5 plays weird Vista music when plugged into car to charge.

[AC Question]

When I try to charge me phone with a USB in my car, Pandora stops and I get crazy music (or even animal sounds) that shows up as something about Vista music--WHY does this happen? Most of the time I can't get back to pandora. Today it also started reading saved voicemail messages!!! How do i stop this craziness? Thx.
