<p>I've searched around a bit in the small amount of iPhone/iPod Touch development information available and couldn't find anything for or against.  Can an application find out information about currently playing song on iPhone/iPod Touch?  Since the music can continue to play while you are in 3rd party applications, is there a function or library that will give you information about what is playing? (Track, Artist, Album, etc.)  I know generally that applications are sand-boxed but thought maybe there was a way.</p>

As I understand it, these are equivalent as far as scoping is concerned:
```
```
function a() { ... }
```
```
and
```
```
var a = function() { ... }
```
```
