Setting MPMediaItem's artwork

I know I can retrieve an MPMediaItem's artwork by doing the following:

MPMediaItemCollection *collection;
/* Get media item collection here */
MPMediaItem *item = [[collection items] objectAtIndex:0];
MPMediaItemArtwork *artwork = [item valueForKey:MPMediaItemPropertyArtwork];

I would like to replace the artwork image with another. How would I accomplish this?

I tried the following but it doesn't work.

UIImage *newImage;
/* get image here */
MPMediaItemArtwork *artwork = [[MPMediaItemArtwork alloc] initWithImage:newImage];
[item setValue:artwork forKey:MPMediaItemPropertyArtwork];

An run-time exception is thrown with the following message:
this class is not key value coding-compliant for the key artwork.

MPMediaItems are immutable - you can't change anything in the iPod library using the API.
