That's what I get in my JJ1:

HH94 :

Day and Evening music are same.
Night music is nice touch on 'Holy Night'.
It's used in HH94 ending cutscene as well.
Same bonus music as in other JJ1 episodes.

HH95 :

Candion's music is brand different than HH94's evening.
Didn't check bonus level music, but I think it's Exoticus in HH95.
Bloxonius remains problemless.

Notice how I didn't compare musics from secret HH94 level and secret Candion level. I assume they have same music, but I can't hear music in JJ1 now. >(
