Title Screen theme
"The title theme from previous games, done in a Japanese style while keeping its essence. This song is meant to belie the tense atmosphere of "Now, let the Danmaku begin!". Frankly, I think this song isn't necessary, but it's also meant to restrain the player's excitement while awaiting Danmaku."
In practice the title screen theme *is* used with a lot of SFX going on due to menu selection and so on, however this track still ended up using all six FM channels. The perfect fifth (well, 12-TET) playing at a quaver after the bass note reminds me heavily of Disunified Field Theory of Magic, although obviously there are more than that one song that do this.
