Strangely, I really don't mind the EoSD songs. For the less advanced instrumentation, there was a more natural rhythm and composition IMO compared to some of the songs of the later games. Mostly percussion-wise. My nitpicks with some of the PCB and IN tracks in general is that there was a lot of....overwrought percussion.
The only thing I find at fault in with Septette is the weird way it's shifted a quarter flat, or something. Made trying to figure it out on piano and guitar kind of a pain.
