I'm kind of hoping they redo at least their first three songs
-Kanojo because the original is only 5 of the members (which 2 aren't even members anymore)
-Ten Made Nobore! (prolly because it needs it, although I would be OK if it didn't happen since it's a unison track)
-Oheso (Kaneko and Kosuga are gone (and less so the other girls who left that were involved here))
