No Doubt sues Activision over inappropriate use of their avatars in Guitar Hero

Famous rock band No Doubt has sued Activision over the use of its avatars in the game Guitar Hero 5. No Doubt says that the deal it signed with Activision only permitted the avatars to be used when playing No Doubt songs. The problem is that Activision has it set up that you can play any song in the game with the No Doubt avatars. That I'm even writing about this is rather depressing.
