Earth Rise, Gliese 581, Heliopause, Bunpasong, Cosmic Bird, Hinotori.
The six songs that make up Namco's little space series of Namco Originals (SORA-VI will be up on song series page very soon!), and one series that Namco has not given up on since it arrived on Taiko Wii 2. All of them with their own unique brand of music and tones that emphasize how varied and unknown our universe is.
Though not all of the SORA songs have obvious astronomy references (SORA-IV), there are tons and tons of other space-related stuff that could potentially fit into a SORA-VII, if it gets made. What would you name SORA-VII, and what musical style do you want it to have? Do share~!
