iPhones app

It sucks
Any time I try to listen to my music in my car I have to close the app and open my music agin, I was blaming my phone or either my car, but guess what my phone is iPhone 6s now and Im driving a cx5-2016
Problem is the app, no matter what if I turn the engine off its all gone I have to start over
Fix it please...
Or even if I pause a song
By the way dont change the apps structure; like changing sync to my songs !?!?
its so annoying for the user. when we get use to something and you just simply change it !
