Castlevania: Lords of Shadow - Super Castlevania IV Soundset (SNESology)i think that the music as a general in MOF improved from LOS since i remember various times actually enjoying the music (like in the library) until a stupid hunchback appeared and changed the tune into battle even if he was dead even before the tune started...
but LOS did have some pieces that I genuinely like, and with that downgrade, the two biggest things that fail in both LOS and MOF music IMO is more regarding design that composition, not being able to let any tune sink through gameplay having thrown a mash up of songs every 5 seconds while you kill enemies, explore and kill more enemies, and the fact that the tunes repeat themselves is what really kill LOS and MOF music.
