I can't exactly predict what could be on it, considering there wasn't a whole lot of singles this year
My predictions
C-ute - Jinsei wa STEP! and/or Naze Hito wa Arasoun Darou? (I could also see Iron Heart because of how close it was to be released in 2016)
Momusu - Tokyo to Iu Katasumi (really couldn't think of a 2nd song, maybe One and Only because like C-ute, that single was released so close to 2016)
ANGERME - Tsugitsugi Zokuzoku , Ai no Tame, or Umaku Ienai
Juice=Juice - Karada Dake ga Otona ni Nattan ja nai and KEEP ON Joshou Shikou!! (though not sure if this upcoming single will make the cut, so this is questionable)
Country Girls - Boogie Woogie LOVE & Dou Datte Ii no
Kobushi Factory - Sakura Night Fever (or Chotto Guchoku ni! Chototsu Moushin for popularity) & Samba! Kobushi Janeiro
Tsubaki Factory - Not sure because they're still indies, but I could see both Kedakaku Sakihokore! & Hitorijime making the cut
Buono! - Solatido ~Nee Nee~ for sure!
OTHERS
Maybe both of NEXT YOU's songs? (Next is you! & Otona no Jijou)
3 Theater songs (Kizetsu Suru Hodo Aishiteru!, Higashi no Chihei, Nishi no Towa, and MODE)
Maybe the some unreleased tour songs (Wakacchanai, Jouro, two of those Country Girls' songs, more?)
EDIT: if Neowing is right then we'll also see those 3 remixes that C-ute, Momusu, and ANGERME released
