This is "Rosalina in the Observatory 1 - Super Mario Galaxy" / "Comet Observatory 1 - Super Mario Galaxy", but digitally re-edited into a minor scale.
IMPORTANT NOTE: None of these (besides the ones that I modify) belong to me. They belong to Nintendo. Credits goes to them.
DISCLAIMER: This may be the only time that I'll ever turn Super Mario Galaxy's version of Comet Observatory into a minor scale since the other versions I tried didn't sound either very good or accurate to what I would think sound like if it was in minor key. Another issue is there’s some distracting high-pitched and/or low-pitched whine in certain parts of this music that weren't in the original, which I could NOT fix. Therefore I had to manually fix some of the notes so it wouldn't sound very off. This is obviously not perfect, but I did my best. It's supposed to be based off of this, so credits goes to this user as well: https://www.youtube.com/watch?v=C8Z_FwQYSo8
