How to get my Iphone 4s music not to play from the lock screen in silent mode?

Basically I need to keep my phone from allowing anyone to use music when its locked, but I know there's no possibility of that--so I was just wondering if you could help me figure out how to keep it on silent? Like, when I play videos in silent mode there's never any voice unless I turn it back to normal mode, but its not the same for music, they still play loud and clear. Help?

(If you have another way of keeping my music from being accessed on the lock screen then that would be just as helpful, thanks X)

I was just wondering. I usually use the computer, and sometimes even 4-6 hours. Does this make you get glasses? I also usually go on my iPhone at night, with out any lights. It's weird because some people who don't even use the computer have glasses, but I use it a lot and I don't have glasses

IPhone problem! Won't charge

So about 3 weeks ago I got an I-Charge it's basically a little box where you plug in your phone and it will automatically charge anywhere you are. So I was using it perfectly fine. Today I plugged in my phone and it said 'charging is not supported with this accessory'. My I-Charge works with other iPhones except mine. My iPhone only charges with original charger that came with a phone. Is there anyway I can solve this problem?
