Green Day, Metallica and Madonna music videos will be returning to YouTube. Ending a nine-month standoff, YouTube said on Tuesday that it had reached an agreement with the Warner Music Group that would return the label’s music videos to the video Web site.

Warner Music had demanded that its videos be removed last December after licensing talks stalled with YouTube, a unit of Google. The deal means YouTube has agreements in place with the country’s four major record labels and four major publishers.

As it did in its previous deal, YouTube will share advertising revenue with Warner. But the terms of the new deal are believed to be more advantageous for the music label, although the companies refused to comment on the terms or the details of the negotiations.

The San Carlos video site, which is owned by Mountain View Internet giant Google, announced on its official blog today that it has reached a deal with Warner Music Group that “covers the full Warner catalog and includes user-generated content containing WMG acts.”

“With Warner on board, we now have artists from all four of the major music labels and publishers together with hundreds of indie labels and publishers on our platform,” Chris Maxcy, YouTube’s director of partner development, wrote on the blog.

“Warner will also be able to sell their own ad inventory and will use our Content ID technology to claim and monetize user-generated videos uploaded to YouTube by Warner Music fans,” Maxcy wrote.
