Callisto is also a moon of Jupiter. Its surface is desolate and heavily cratered, much like our moon. The music is sad, mournful for this lonely moon. Rhea is the second largest moon of Jupiter. A simple, almost oriental, theme is heard above the fray.
Titan is slow and brooding, with dark horn-like textures and low melodic themes.
Titan is Saturn's largest moon. It is thought to have life because of its hydrocarbon-rich atmosphere. However, the same atmosphere, thick and rust color, obscures the surface. Iapetus is the third largest moon of Saturn. It is quite unique in that half of it is black and the other half white.
