I've noticed this for quite a while now, but as I got older, I began researching Motoi Sakuraba's works.
Throughout his career, his style has changed ever so slightly.
One thing that seems to be constant is the style of his battle themes.
The point of this thread is to compare music from his other games to his music from the Golden Sun series.
From 0:36 to around 0:50, it sounds like the 2nd battle theme in Dark Dawn, but both battle themes seem to have elements from the Tales of Rebirth one.
