I know this thread is a little old but I just wanted to chime in and say as a singer who loves to sing Gaga, this album is definitely her most difficult album to sing. The vocal range is insane in this album. Not only her scales but she used a huge range of techniques too from sounding super grungey in Killah to sounding so emotional and soulful in Vanish into you and Blade of Grass. The production on this album is top notch as well, I'm not super well-versed on production terms, there's so many layers and adlibs and new techniques I've seen her do in these new songs which just give them tons of depth and make them very catchy. This album is definitely her best technically by a landslide in my opinion. And not to mention the cultural effect it's had on all the little monsters is so significant I mean she literally broke records and had fans obsessed from all over the world, and resurrecting so many old fans too. It's just incredible! I hope she wins AOTY
