Interesting comments, that's exactly where YouLicense.com the open online music licensing marketplace comes in to play. YouLicense lets indie artists interact with video game makers and allows them to quickly and inexpensively license their music.
Warner's decision maybe the right business decision from their end, but it opens the doors for many other labels to offer their music to the video games industry. With resources and marketplaces like http://www.youlicense.com , video game makers can license music through a more convenient channel.
