Notes Uncertain or tentative taxa are in small text; |
gollark: Random pop songs tend to be "uplifting", but also extremely dull.
gollark: Well, that might be nice, but my main concern is it not being boring.
gollark: I only listen to music with guitars and screaming. Other "music" is not real.
gollark: Yes.
gollark: "Creation of Earth (Sun)" is also boring.
