The catchiest song on the album is probably Sinner's Prayer but it wouldn't make sense as a single.
the singles should go as follow:
1. Perfect Illusion
2. Million Reasons (already doing good on iTunes, some promotion here and there and a nice mv and she's got it)
3. A-Yo
4. Diamond Heart
5. Joanne/Angel Down
Just Dance - Bad Romance - Marry The Night - Aura - Diamond Heart
LoveGame - Alejandro - Born This Way - Venus - A-YO
Paparazzi - Monster - Government Hooker - G.U.Y. - Joanne
Poker Face - Speechless - Judas - Sexxx Dreams - John Wayne
Eh, Eh - Dance In The Dark - Americano - Jewels N' Drugs - Dancin' In Circles
Beautiful, Dirty, Rich - Telephone - Hair - MANiCURE - Perfect Illusion
The Fame - So Happy I Could Die - Scheisse - Do What U Want - Million Reasons
Money Honey - Teeth - Bloody Mary - ARTPOP - Sinner's Prayer

Paper Gangsta - Fashion of His Love - Fashion! - Angel Down
Brown Eyes - Highway Unicorn - Mary Jane Holland - Grigio Girls
I Like It Rough - Heavy Metal Lover - Dope - Just Another Day
Summer Boy - Electric Chapel - Gypsy - Angel Down (Work Tape)
'Joanne' needs to be performed at the Grammys (really simple, just her and a mic).
There's a chance because (thank god) the Super Bowl is before the Grammys this year.
If it was the other way round there's no way she would do a Grammys performance.
A slightly more-PG Dancin' in Circles would make the best second single imo. As far as the beat and style goes that song is interesting compared to what's on the radio at the moment. The fact the beat is almost tropical/reggae and her vocals are the most TFM in a long time means a lot.
A-Yo is cute but it's uneventful af. It's not catchy 'bar' the A-Yo refrain, the public will hate it lol.
