Well, I specifically disliked
End of Eva's soundtrack. Well, more so, I really disliked the soundtrack dissonance. Komm Susser Todd is a nice song, but I hate the name, and hate how it was used.
And Thanatos does not deserve to be an upbeat jazzy ending theme.
The only good use of soundtrack dissonance in it was with Bach's Orchestral Suite Air.
On the other hand, I have listened to the main series soundtrack (three discs) many times (not including the multitude of versions of Fly Me to the Moon, though), and I've even made a custom playlist of it that arranges them into three "Acts", complete with intermissions, and I've also given each of the tracks a new name, such that the names match better with each other and with what they represent in the show.
And you don't know how much I've listened to the third disc (think much of the music from episodes 25-26) at various difficult times during my undergraduate college years.
So...in short, I love the soundtrack, and I feel a deep emotional connection to the original ending.
