The forthcoming version 3.0 does have this capability. Release notes include this

iPod Library Access

Several new classes and protocols have been added to the Media Player framework (MediaPlayer.framework) to allow access to the user’s audio library. You can use these classes to perform the following tasks:

• Play audio items from the user’s library. This support lets you play all audio types supported by the iPod application.
• Construct queues of audio items to play back.
• Perform searches of the user’s audio library.
• Access the user’s playlists (including smart, on-the-go, and genius playlists).

For more information about the classes of the Media Player framework, see Media Player Framework Reference.
