Okuda Hanako’s classic song “Kawaranai Mono” (“The Unchanging”).
Released in 2006, it’s well known as an insert song for the film The Girl Who Leapt Through Time, and its orthodox J-pop ballad style has garnered support from many listeners.
The song’s vocal range spans mid2 A# to hi C#, which is a very comfortable and relatively narrow range for female singers.
