How come Endless Climbing is one of Rose's theme when it appears more in Dave's themes such as Clockwork Melody, Clockwork Contrivance and Clockwork Sorrow?

Looking at the credits, you can blame Clark “Plazmataz” Powell for that! Seems like it’s not necessarily either of their themes? Like. It was used for Rose, but the song may not have been made for that purpose, and then it was adapted by Clark for the ‘Clockwork’ songs which may have led to it sticking as a Dave theme. It doesn’t necessarily sound Dave-ish though. Maybe we can say it’s more of a Derse Kids Theme?
