Apple has seeded iTunes 11.1 beta 2 to developers for testing.

This version of iTunes includes the new iTunes Radio - a great new way to discover music. iTunes Radio requires OS X 10.7 or later and is available only in the U.S.

It's unclear what exactly is new in this update. Perhaps Apple addressed the same issue that was fixed by iTunes 11.0.5 released today.

Developers can download the update from the Dev Center linked below.
