Could you please elaborate then? I can't hear anything in Eastern Dream that pertains to Septette. Border of Life and Japanize Dream are only similar because they're both based on Sakura Sakura. I actually rechecked Future Dream before I posted to make sure I wasn't mistaken.
EoSD - Compare the beggining of Eastern Dream to the part of Septette thats starts at 1:23 - it's very similar but slower.
PCB - I thought Sakura Sakura and Japanize dream were the same song "Sakura Sakura ~ Japanize Dream" Anyway, in "Sakura Sakura ~ Japanize Dream", at :30 you can hear a piano-ish melody in the background. This sounds very similar to "Bloom Nobly, Cherry Blossoms of Sumizome ~ Border of Life" at 1:05.
IN - This one I'm unsure about. Basically the piano in the beggining of Eternal Dream ~ Mystic Maple is "kind of" like the fast intro part of Lunatic Princess. But not really. I would note, however, that there are two final bosses, and that Mokou's theme has some similarity to Kaguya's. (They start kind of softly, then shift into a fast repetative intro) Otherwise idk, IN is just wierd.
PoFV - The intros to Another Dream and Eiki's theme are vaguely similar. Another Dream has a three note repetition at :29. Eiki's theme does the same thing at :50.
MoF - You agreed to that one earlier.
SA - Compare Future Dream at :22 to Nuclear Fusion at :50. Otherwise its more in the "feel" rather than direct similarity.
UFO - You agreed with that one too.
TD - No idea, unfamiliar with the soundtrack.
Clearly, some of these are just vaguely similar, but still the similarities are close enough (imo, anyway) Also I'm not familiar with Fairy Wars, if that even counts.
Sorry about the late reply I've had no internet access.
