I wish Roseland was in the middle of her mid-era blackout so she would atleast be somewhat in the public eye while replanning things. Now its getting in the way of her focusing on G.U.Y
G.U.Y. is arguably the best single choice on the album because it is structured and produced so reminiscently to her early singles. It has the Gaga brand written all over it, it's in the minor key, it has the spoken-word breakdown, the hook. It's the most Gaga-esque song on the album.
Aside from this, if she ever wants to smash the charts again, she needs RedOne. I'm not just saying this because he's produced all her smash singles in the past - he's the only one that truly understands how to produce a hit Gaga song. He's done it for others and it hasn't worked. His formula for Gaga has worked time and time again, and it's clearly Gaga tried to emulate that formula while working with other producers and that didn't work either. They need each other.
