The previews are awesome! Of course they're polished as f---, but the point is that they sound great! poker face sounds surreal because her voice was so high-pitched there I almost couldn't believe it, but in the end I like how the edited version turns out. M is amazing too. It's in the original key and I'm really happy that she pulled it off really well (even from the actual fan recording of the concert we got the other day). I'm really looking forward to the BluRay! I hope there are bonuses and they are amazing
