Can't believe we're back in the most exciting part of being a fan: the build up of teasers for an album. This is why I despise surprise releases, you don't get the little hints in tweets and interviews which makes it all worthwhile.
In videos from the Superbowl audience her voice sounds the same as it always does. I believe Goldsoundz when he said they just had top range production for the TV broadcast which made her vocals sound great.
