I hope this album will just be simple songs about things like life and emotions and all that. I am a fan of the second album where Yanagi Nagi collaborated with Jun Maeda, but I definitely prefer for Maeda to write an album with songs that donāt tell a story (especially if no ones gonna adapt them sadly). His writing for these simple songs are quite better.
I donāt think itās Lia, nor Aoi Tada. I feel like their voices are more suitable for noteworthy OP/ED/Insert Songs.
I hope itās not Anri if heās planning to do many Hard instrumental songs. Its already been shown with End of the World that Anriās voice is too soft for those type of songs (and Jun Maeda loves making those type of songs). But Iād definitely want her if heās making many mellow songs, because her voice excels there. I mean, Kimi No Moji and the song that she did alongside End Of The World is quite beautiful with her voice.
I am 95% certain that itās Anri Kumaki though. When he was making Love Song 2, he worked with Yanagi Nagi. He only knew of Yanagi Nagi through working on Rewrite. So we can assume that the singer of the album will most likely be someone affiliated with Key. 2% of my suspicion is on Runa, and 3% is on the girl who sung Towa No Hoshi E or the Angel Beats! 1st Beat ED.
