Harmonix and MTV Games have confirmed the release of a title update for Rock Band on the Xbox 360 that will make it possible for owners of the original Rock Band to export 55 tracks from the original Rock Band disc for play in the soon-to-be released Rock Band 2.

Beginning September 4th, the title update will add an “export disc” tab under the extras option in the Rock Band menus, allowing owners of the original Rock Band to expand their Rock Band 2 library to include 55 tracks from the original Rock Band track list for a fee of $4.99 or 400 Microsoft Points if you rather.

In addition, this patch is required for all future downloadable content releases for Rock Band. Previously purchased DLC will not be affected.
