"Cobalt Coastlands 1-1", which is one of the two possible themes that play during midday while in most locations of the Cobalt Coastlands, is initially purely a remix of Route 209's theme. However, upon defeating the Noble Arcanine, "Cobalt Coastlands 1-2" instead plays, which is essentially the same as the former theme, but with additional features of Route 209's theme added in, as well as features of Hearthome City's theme.
Although not explicitly stated in the Super Music Collection, Route 210's theme also appears to be referenced at the beginning of "Cobalt Highlands 1-1", as well as its successor.
The second theme that could play during midday, "Cobalt Coastlands 2-1", does not initially feature any motifs. However, upon defeating the Noble Arcanine, "Cobalt Coastlands 2-2" instead plays, which is essentially the same as the former theme with features of Canalave City's theme added in.
The music that plays in Firespit Island is a remix of Stark Mountain's theme.
