                                  Introduction

      This Amendment No. 15 amends and supplements the Schedule 13D, dated
September 28, 2001, as amended to date (the "Schedule 13D"), filed with the
Securities and Exchange Commission by MM Companies, Inc., formerly known as
musicmaker.com, Inc. ("MM Companies"), Jewelcor Management, Inc., Barington
Companies Equity Partners, L.P., Ramius Securities, LLC and Domrose Sons
Partnership with respect to the common stock, $.001 par value, of Liquid Audio,
Inc., a Delaware corporation (the "Company").


      Item 4 of the Schedule 13D, "Purpose of Transaction," is amended by adding
the following:

      On August 20, 2002, the Company filed an action against MM Companies and
Steel Partners II, L.P. in the United States District Court in the Southern
District of New York (the "Southern District") seeking, among other things,
injunctive and other relief to restrain and enjoin MM Companies from conducting
further solicitation of proxies of the Company's stockholders. On such date, the
Company also filed with the Southern District a motion seeking, among other
things, a preliminary injunction enjoining MM Companies from conducting the
solicitation of proxies described in the preceding sentence. A hearing with
respect to the Company's motion has been set for September 5, 2002 in the
Southern District. In response to the filing of the action by the Company in the
Southern District, on August 22, 2002, MM Companies issued a press release, a
copy of which is attached hereto as Exhibit 99.23.

      On August 23, 2002, the Company requested that the Southern District issue
a temporary restraining order against MM Companies and Steel Partners II, L.P.
prohibiting MM Companies and Steel Partners II, L.P. from soliciting proxies of
the Company's stockholders pending the hearing on September 5, 2002. On August
26, 2002, after hearing oral arguments from all parties, the Southern District
denied the Company's request for such an order.

      Earlier, on August 22, 2002, MM Companies sent a letter to each of Raymond
Doig, Stephen Imbler and Ann Winblad, members of the Board of Directors of the
Company, in which, among other things, it urged such non-management board
members to reconsider their support of the Company's business strategy and the
proposed merger with Alliance Entertainment Corp.

      On August 26, 2002, MM Companies filed an action against the members of
the Board of Directors of the Company (the "Director Defendants") and the
Company in the Court of Chancery of the State of Delaware In and For New Castle
County seeking, among other things, injunctive and other equitable relief (a) to
invalidate the decision of the Director Defendants to amend the Company's Bylaws
which increased the size of the Board of Directors from five to seven members,
(b) to invalidate the decision of the Director Defendants to appoint two
additional members of the Board of Directors of the Company and (c)
preliminarily and permanently enjoining the Company and the Director Defendants
from changing the size of the Board of Directors until the results of the
election of board members at the 2002 annual meeting of stockholders is
calculated and certified.

      On August 27, 2002, MM Companies sent a letter to the Board of Directors
and the Secretary of the Company. In such letter, among other things, MM
Companies notified the

                                      -2-



Company that if the expansion of the size of the Board of Directors is not
rescinded or invalidated, MM Companies is making a conforming change to its
proposal to be presented to shareholders at the Company's upcoming annual
meeting to increase the size of the Board of Directors such that if the number
of directors of the Company is seven, the proposal of MM Companies is to
increase the size of the Board of Directors of the Company to 11 members. A copy
of such letter is attached hereto as Exhibit 99.24.

      Item 7 of the Schedule 13D, "Material to be Filed as Exhibits," is amended
by adding the following:

      99.23 Press release of MM Companies dated August 22, 2002.

      99.24 Letter dated August 27, 2002 from MM Companies to the Board of
            Directors and the Secretary of the Company.


                                      -3-

the undersigned, the undersigned certify that the information set forth in this
Statement is true, complete and correct.
