How can I disable the music player on an iPhone 4S lock screen How do I disable the music player controls on the iPhone 4S lock screen?
I've tried setting the "triple click home button" to "off", but it didn't help.
I'm afraid this is not possible by default on your iPhone. It's a feature in iOS and there is no easy way to disable this.

You could jailbreak your iPhone, you can buy Springtomize for $2,99 which will allow you to do what you want. Just turn on the "Hide Top Bar" option.
