I'm sooo late, I've been out all day and thinking about this.
Roar's vocals are so good Thank you for this!!
Edit: You can totally hear the emotion in her voice in Ghost! and BTGOG sounds so great, just like the live version. and International Smile is listenable now.
Hopefully when you get the Britney Jean stems, ARTPOP stems and other album stems; you can make more acoustic sessions because they really explore a different region of songs which aren't so noticeable with the production on the album tracks.
Just finished listening to the whole album, truly amazing.
Although, International Smile sounded different to the preview... and there was no "please be seated" announcement. I was most excited to hear that one, and I'm not sure if I liked the changed version as much as the preview. It was also really, really short. Overall though, fantastic!
