Looked up composers. The one you liked the most has worked with Gana on Bokutachi wa Tsukiatteiru. Neru was originally a Gana member so it makes sense. Ironically, Akira Sunset worked first with Nogi and his credits are dominated by Nogi songs. Hatsukoi Door definitely sounds more modern Nogi with 3gen than 1gen/2gen Nogi. Hatsukoi Door has neither a 1gen or 2gen member from Nogi can explain the music direction. It's mainly 3gen and Umezawa joining. Next SakamichiAKB song will probably have a Team 8 member to center the song due to their push in AKB48. That will certainly sound like a modern AKB song. And to stay on topic I hope to see more songs from Kazuhiro Sakuma (Dare no koto) and Jun Aiba (Getsuyoubi) for Keyaki in the future. Composers with one song as debut which are both Keyaki-like. But I won't say no to 48G composers as they have nailed B-side songs like Te wo tsunaide or A-side like Kaze ni, SekAi, etc. And BugBear for riot songs (SaiMajo, Fukyouwaon, Bokutachi no Sensou). This will probably surprise many, same duo who composed W-Keyakizaka no Uta did Garasu Wo Ware! as well.
