Exhibit 4.24

GUARANTEE

GUARANTEE, dated as of December 8, 2011, made by Warner Music Group Corp. (the “Guarantor”), in favor of holders (the “Holders”) of the 11.50% Senior Notes due 2018 (the “Notes”) of WMG Acquisition Corp., a Delaware corporation, (the “Company”) issued pursuant to the Indenture, dated as of July 20, 2011, by and among WM Finance Corp. (the “Initial Issuer”), the guarantors party thereto and Wells Fargo Bank, National Association, as Trustee (the “Trustee”), as amended by the Supplemental Indenture, dated as of July 20, 2011, by and among the Company, as successor by merger to the Initial Issuer, and the Trustee (such indenture, as the same may be amended, restated or supplemented from time to time, the “Indenture”).

The obligations of the Guarantor pursuant to this Guarantee, are expressly set forth below, and the precise terms and limitations of this Guarantee are as set forth below.

SECTION 1.01. Unconditional Guarantee.

The Guarantor hereby unconditionally and irrevocably guarantees, on a senior unsecured basis to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company to the Holders thereunder: (a) (x) the due and punctual payment of the principal of, premium, if any, and interest on the Notes when and as the same shall become due and payable, whether at maturity, upon redemption or repurchase, by acceleration or otherwise, (y) the due and punctual payment of interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Notes and (z) the due and punctual payment and performance of all other payment obligations of the Company to the Holders thereunder, all in accordance with the terms hereof (collectively, the “Guarantee Obligations”); and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the due and punctual payment and performance of Guarantee Obligations in accordance with the terms of the extension or renewal, whether at maturity, upon redemption or repurchase, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, for whatever reason, the Guarantor shall be obligated to pay, the same immediately. An Event of Default (as defined in the Indenture) shall constitute an event of default under this Guarantee, and shall entitle the Holders to accelerate the obligations of the Guarantor in the same manner and to the same extent as the obligations of the Company.

The Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same, whether or not this Guarantee is affixed to any particular Note, or any other circumstance which might otherwise constitute a legal or

equitable discharge or defense of the Guarantor. The Guarantor hereby waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the Guarantee Obligations. This Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Company, or any custodian, trustee, liquidator or other similar official acting in relation to the Company, any amount paid by the Company to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. The Guarantor further agrees that, as between it, on the one hand, and the Holders of Notes, on the other hand, (a) subject to this Guarantee, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of this Guarantee.

SECTION 1.02. Limitation on Guarantor Liability.

The obligations of the Guarantor under this Guarantee shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of the Guarantor that are relevant under Title 11, U.S. Code or any similar Federal, state or foreign law for the relief of debtors, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to this Guarantee, and after giving effect to any collections by the Company from, rights of the Company to receive contribution from or payments made to the Company by or on behalf of any other guarantor of the Notes in respect of the guarantee obligations of such other guarantor with respect to the Notes, result in the obligations of such guarantor under its guarantee not constituting a fraudulent transfer or conveyance.

SECTION 1.03. Execution and Delivery of Guarantee.

The validity and enforceability of this Guarantee shall not be affected by the fact that it is not affixed to any particular Note.

The Guarantor hereby agrees that this Guarantee shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

If an officer of the Guarantor whose signature is on this Guarantee no longer holds that office at any time after the date hereof, this Guarantee shall nevertheless be valid.

This Guarantee will be released and terminated and of no further effect:

(b) upon the release or discharge of the guarantee by the Guarantor of (i) the Company’s 9.50% Senior Secured Notes due 2016 issued pursuant to the Indenture, dated as of May 28, 2009, by and among the Company, the guarantors party thereto and Wells Fargo Bank, National Association, as trustee, as amended by the Supplemental Indenture, dated as of May 23, 2011, among the Company, WMG Holdings Corp., the guarantors party thereto and the trustee, as amended by the Second Supplemental Indenture, dated as of July 20, 2011, among the Company, WMG Holdings Corp., the guarantors party thereto and the trustee or (ii) the Company’s 9.50% Senior Secured Notes due 2016 issued pursuant to the Indenture, dated as of July 20, 2011, by and among the Company (as successor by merger to WM Finance Corp.), the guarantors party thereto and Wells Fargo Bank, National Association, as trustee, as amended by the Supplemental Indenture, dated as of July 20, 2011, by and among the Company, as successor by merger to the WM Finance Corp., and Wells Fargo Bank, National Association, as trustee.
