I had never played the original Hollow Knight, but watched a streamer play the first half an hour or so of Silksong and immediately bought it in large part for the soundtrack. From the lush harps and gentle woodwind of Moss Grotto, to the music-box melodrama of Cogwork Core, this is a godly soundtrack. A bit gutted it didn't include the Threefold Melody, violin Flea theme, or more ambient soundtracks like the Ducts or Wormways.
Favorite track: Cogwork Core.
