This is not the case the only known apps that Trump the Music app is the phone and FaceTime which will mute your played songs till the call is over then it will resume
The Music app is a Wonderful pure Multitasking app that not only plays in the background while using almost all the other apps but also shows up on your lockscreen and Control Panel even plays when your screen is off for maximum battery savings
To fully close the Music app Double click on the home button and swipe the app up and away or just choose to pause it for later
My advice if you have the storage load a lot of Music and spice up your iPhone experience with your favorite tunes
