Let's talk about why Undyne uses the Ruins lietmotif. One theory is that it's because it's also Waterfall's lietmotif. My theory is that it isn't even a Ruins lietmotif at all. It's a determination lietmotif. This is because this theme, specifically the one Undyne uses.. is actually "Don't Give Up". Now, Undyne is determined, is she not? So, perhaps it might even be more suprising if she DIDN'T use that lietmotif, especially during her fight, where the whole theme is she's determined to strike you down.

So, yeah. The Ruins lietmotif isn't actually about the Ruins. It's about determination. I actually have a thread of my own where I analyze all the important themes. (As in, music themes.) I think this is right. The Snowdin Town leitmotif could be is friendship. This would explain why it's in Hopes and Dreams and the Dating! songs.

Also, the Once Upon a Time leitmotif could be for hope. It's in many songs and that is a theme presented throughout the game.

The Ghost Fight leitmotif might not be used to show similarities or relationships between the bosses themselves, but more in the reasons why they fight or how Frisk feels. In all of these fights, you were just passing through and a fight jumped out of nowhere... it could be something to do with that?
