I agree!! And I really love the latter part of the chorus..... I actually composed something similar to it a few weeks ago - I'm so glad to hear a better version of it :3
Keiko got her usual 2 lines in Yane no Mukou ni I dont see anything different from her past 2 lines in songs that could be loved more than them. Lead vocal Wakana with Hikaru singing some parts. I dont see similarities with Kagayaku however. I will need some time to get used to the song.
^ My guess is that the leaked version was one of the LE versions. Only the RE has the full instrumental.

Well, I said Yane no Mukou ni would be the deciding factor in whether or not I get the single or not; and I've decided not to. It's not worth shelling out $30-$40 for right now. I might pick up the RE at a later time.
I think my favorite part of this single is the instrumental version of moonfesta ~minna no uta~. I haven't heard the full instrumental yet, though, so that might beat the shorter instrumental. Either way, it's amazing!
I don't think I listened to Yane no Mukou ni enough to give my overall opinion, but so far it's just 'okay' to me. I will say that I actually dislike Keiko's two lines at the beginning of the second verse. I prefer her two lines at the beginning of the bridge(?). I'm not sure why, though. I like when Keiko sings a little higher (Mune no Yukue solo), but I just didn't think it fits there... Also, the beginning of the first verse sounds really familiar to me. I think it reminds me of a piece of manten.
I'd say more, but I should probably listen to Yune no Mukou ni and moonfesta more times to give a more detailed response.
