IPhone 5 music playing symbol won't show. Why?

So it's nothing big at all, but since I got iOS 7 on its release date the music symbol in the top right corner won't show. You know, by the battery percentage and stuff. It's been annoying me for some reason because I'm so used to having it there on my iPod! My iPod has iOS 7 and it shows it. Help me please. I appreciate any info you guys have!

Strangely, Apple hasn't included it in the update. Annoying right?
