Exhibit 99.1

[WMG Logo]

May 11, 2011

As you may know, on May 6, 2011, Warner Music Group Corp. (“WMG”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with an affiliate of Access Industries, Inc. (the “Acquirer”) pursuant to which the Acquirer will purchase outstanding shares of WMG common stock for $8.25 per share (the “Merger”). The transaction is subject to a number of conditions, including approval by the stockholders of WMG. If the transaction closes as anticipated, WMG’s stock will no longer be publicly traded after the closing. We expect the Merger to close in the third calendar quarter of 2011.

Pursuant to the Merger Agreement, all options outstanding on the date of the Merger, whether vested or unvested, will be cancelled and each holder will be entitled to receive a cash payment equal to the product of the number of shares of common stock subject to his or her option multiplied by the excess, if any, of $8.25 per share over the option exercise price, less any applicable withholding taxes. So, for example, if you were granted 10,000 WMG stock options with an exercise price of $6.25 in March 2010 and assuming the transaction closes on September 30, 2011 and you have not exercised your vested options and you remain employed with WMG on such date, 25% of your options (2,500 shares) would be vested on the closing date. However, as described above, since the exercise price of your options is below the $8.25 per share price payable in the Merger, you will be entitled to a cash payment equal to $2 per share “spread” on all 10,000 of your “in the money” options (less applicable withholding taxes), regardless of vesting. “Out of the money” WMG options with an exercise price equal to or greater than $8.25 will be cancelled immediately prior to the closing of the Merger with no cash payment to the holder thereof.

During the period between now and the Merger closing date, WMG stock will continue to be publicly traded and any holder of vested WMG stock options may exercise those options, subject to any blackout periods and/or any other trading limitations that may be in effect from time to time as applicable to the particular optionholder.

We will provide additional information to optionholders closer to the date of the planned Merger closing.

Please note: All aspects of your options are governed by the terms and provisions of the WMG equity plan under which they were granted, your particular option award agreement and the Merger Agreement, and not by this memorandum.

Feel free to contact Trent Tappe, **********, if you have any questions regarding the subject matter of this memorandum.
