"UMG has claimed some or all audio content in your video. This claim was made as part of the YouTube Content Identification program. Your video is still live because UMG has authorized the use of this content on YouTube.
Your video is still available because UMG does not object to this content appearing on YouTube at this time. As long as UMG has a claim on your video, they will receive public statistics about your video, such as number of views. Viewers may also see advertising on your video's page."Why the change UMG? In my opinion the second option works out much better for you. And for me of course.
