You have to be more specific 

[andresalv305]

I'm listening to music on headphones and walkman without a moment's notice is the sound goes all keys music all posts notifications

[Uliwooly]

I still don't understand, but if you are listening to music and you get a message, call etc (notification) the music will pause

look I'm using the phone no matter what happens to him and go back to the sound and just put the headphones
