How does changing songs work when using Galaxy Note 5 with a car receiver through USB and bluetooth?

[AC Question]

So far, I haven't used it with a car stereo, and still don't understand how the standard music app works. Even though I don't have shuffle selected, it randomly plays songs from an album rather than playing the tracks in order. Is there a way to change that with the standard music app or will I need a different app?

Then, my next question is how I can change my music when it's plugged into a car receiver via USB. Can I use the stereo buttons or will I have to change songs on my phone? I'm also planning on creating custom playlists where I hope I can change songs when I want.

I use gpm and Bluetooth and it plays music in order unless I select shuffle. I use the media controls in my car to change to the next track
