Item 6 of the Schedule 13D is hereby amended and supplemented as follows:

The Company announced on May 6, 2011 that the Company had entered into an Agreement and Plan of Merger, dated as of May 6, 2011 (the “Merger Agreement”), with Airplanes Music LLC, a Delaware limited liability company (“Parent”), and Airplanes Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub” and, together with Parent, the “Acquiring Parties”). The Acquiring Parties are affiliated with Access Industries, Inc.

The Merger Agreement provides for, upon the terms and subject to the conditions in the Merger Agreement, the merger of Merger Sub with and into the Company with the Company surviving as a wholly-owned subsidiary of Parent (the “Merger”).

Pursuant to the Merger Agreement, at the effective time of the Merger, each outstanding Share (other than any shares owned by the Company or its wholly-owned subsidiaries or the Acquiring Parties or their respective affiliates or by any stockholders who are entitled to and who properly exercise appraisal rights under Delaware law), will be cancelled and will be converted automatically into the right to receive $8.25 in cash (the “Merger Consideration”), without interest. The closing of the Merger is subject to various conditions, including the approval by the holders of a majority of the outstanding shares of the Company’s common stock entitled to vote on the Merger, certain regulatory approvals and the absence of any Company Material Adverse Effect (as defined in the Merger Agreement).

In connection with the execution of the Merger Agreement, Parent and certain stockholders of the Company have entered into a voting agreement, dated as of May 6, 2011 (the “Voting Agreement”), pursuant to which such stockholders, consisting of the Bain Capital Entities, affiliates of Thomas H. Lee Partners, L.P. and Edgar Bronfman, Jr. (collectively, the “Stockholders”) have agreed with Parent, among other things, to vote approximately 56% of the Shares in favor of the Merger and the adoption of the Merger Agreement and against any competing takeover proposals, subject to the limitations set forth in the Voting Agreement. During the term of the Voting Agreement, each of the Stockholders has agreed not to transfer any of such Shares, except as permitted by the Voting Agreement.

The Stockholders’ obligations under the Voting Agreement will terminate upon the earlier of (i) the consummation of the Merger and (ii) the termination of the Merger Agreement in accordance with its terms, including in connection with a Superior Proposal (as defined in the Merger Agreement). In addition, in the event the Company terminates the Merger Agreement to enter into a Superior Proposal in circumstances in which a Company Termination Fee (as defined in the Merger Agreement) has been paid, and such Superior Proposal is consummated, such Stockholders have agreed to pay Parent 50% of any consideration received by them in excess of the Merger Consideration upon consummation of such transaction.

The foregoing summaries are qualified by reference to the Merger Agreement and Voting Agreement, each of which is incorporated herein by reference. A copy of the Voting Agreement is filed as Exhibit 4 hereto and a copy of the Merger Agreement was filed as Exhibit 2.1 to the Form 8-K of the Company filed with the Securities and Exchange Commission on May 9, 2011.

Item 7 of the Schedule 13D is hereby amended and supplemented as follows:
