My first reaction is that this is probably a question for the author 
of the framework rather than for the Cocoa list. The address for that 
is apparently <email_removed>.

On looking through the code, I do have a couple of comments:

Your MP3 object is never released or autoreleased here. Not sure if 
that's a leak or if you just didn't show the complete snippet.

Ditto image and imageArr.

There's a quirk in the fooWithContentsOfURL: methods in Cocoa whereby 
you might get gzipped data instead of the actual content you're 
expecting. It depends on the OS version and the URL scheme, so you 
might want to split up that line a bit and make sure that what you're 
actually getting back is sane.
