Nara
(1st op song), the cheerful Nanairo Symphony (2nd op song)
, the heartwarming Kirameki (1st ed song)

worthy of their playlist.

Others
- Despite being a background piece, "Yuujin A kun wo Watashi no Bansousha Ni Ninmeishimasu",
note the theme which plays before the performers' big performance builds up the pressure of the atmosphere with the piano, while giving a sense of excitement of looking forward to the grand moment of performance with the strings. It captures the mood of the restlessness of a performer preparing to be onstage and the wonder of having their song be conveyed to the audience perfectly and flawlessly.
