The problem here is that the URL has a custom scheme, ipod-library, which can only be used with AVFoundation methods, for example AVAsset objects.

The MPMediaItem Class Reference says this about MPMediaItemPropertyAssetURL:

MPMediaItemPropertyAssetURL

A URL pointing to the media item, from which an AVAsset object (or other URL-based AV Foundation object) can be created, with any options as desired. Value is an NSURL object.

The URL has the custom scheme of ipod-library. For example, a URL might look like this:

ipod-library://item/item.m4a?id=12345

Usage of the URL outside of the AV Foundation framework is not supported.
