The companies also signed a three-year marketing and promotion agreement, in which MP3.com will provide services to Warner such as featured artist pages and e-mails to market and promote artists, said MP3.com officials in San Diego.
"Warner Music will choose the music and videos from our artists that MP3 gets to promote and market for their users," said Jim Noonan, a spokesman for Warner.
Financial terms of both agreements were not disclosed.
In June, Warner and MP3.com entered into a license agreement permitting the use of Warner-controlled recordings on My.MP3.com's streaming software services, which allow listeners to store songs online if they have already purchased them as CDs.
Earlier this week, EMusic.com and several independent record label partners filed a copyright-infringement suit in the federal District Court for the Southern District of New York against MP3.com and its MyMP3.com service. EMusic sells MP3-format versions of recordings controlled by major labels and popular artists, with exclusive digital rights to about 13,000 albums from more than 600 record labels.
In November, a U.S. District Court judge ordered MP3.com to pay US$53.4 million to the Universal Music Group and other record labels to end their copyright suit against the company. Universal and others had filed suit in January, challenging MP3.com's copying of thousands of copyrighted CDs onto its servers to create its My.MP3.com storage service.
At the time of the judgment, Universal granted MP3.com a license for the use of Universal-controlled recordings on the My.MP3.com system. MP3.com subsequently announced it would relaunch its MyMP3.com service with both paid and free versions.
Warner Music Group owns leading record companies such as The Atlantic Group, Elektra Entertainment Group, Rhino Entertainment, London-Sire Records and Warner Bros. Records Inc. It also owns a leading music publisher, Warner/Chappell and WEA Inc.
MP3.com's Web site hosts more than 750,000 songs and audio files posted from more than 117,000 artists and record labels.
