episode 10 and 16 are absolutely the best ones in the series. episode 10 going from an asuka solo then into her singing in 3 different pitches out of nowhere just sounds so beautiful. episode 16 is kind of the same but with 3 different characters also singing in 3 different beautiful pitches. im not good with music so excuse my lack of music knowledge
For those wondering about the copyright stopping people for experiencing these after each episode, it expires in 2029 meaning if the publisher cares enough they can reinclude these endings. The song was written in 1954 and creative works published/copyrighted before 1980 can only be kept copywritten for 75 years!
