The first game has simpler, but more memorable music.
I've played both, and can still remember like 60% of ambient tracks from hk1.

Silksong doesn't have that strong sense of character to its zones.
The narrative use of music is also a lot less impressive. The whole Vessel fight with the use of a somber rendition of the main motif for example.
Masterful and simple use to generate emotion.

Silksong doesn't really pull it off. The complexity adds nothing
