I don't really know. 😅 I'm very ignorant about music.
The ones with louder bass sound probably are the ones I generated in Soundraw (like the one play on the main screen when the animation intro is not playing), since there I could choose the volume of some instruments 😁 Then I usually put bass in the maximum, cos I love bass feeling.
Most of the game musics were generated in Suno, since it seems to do more complex songs.
