The actual details are a bit less convincing than I thought they might be. And there could be some discussion of what it means to license music for use in a game (or in a movie, or as a ringtone). The general population seems to emphasise more of a "rights to use in any context" idea while some musicians find it important to make sure their recordings are only associated with things they can support. After all, it would probably be frustrating for a band following a "Straight edge" hardcore punk ideal to have their music used in a commercial about a Seagram-created caffeinated liquor involving images of recreational drug use, gluttonous meat eating, and promiscuous sexuality... ;-)
