According to the original play, the episode in "The Mystery of the Musical Notes of Balala" is as follows:

"Magic Melody", the opening theme, with individual accompaniments used as background music

"Dream Girl" (Every morning is a new day), the theme song in the film, used as accompaniment music many times in the play

"Balala", ending It is also a classic song in the Balala Little Demon Fairy series

The above tracks can be downloaded by searching on Baidu and entering their full names. I have uploaded an attachment for "Dream Girl", which can be downloaded on Baidu PC.
