The songs enhance the viewing experience, and they are well integrated into the flow of the movie. Usually musicals take you out of the story and provide a space for the characters to sing.
I actually think that's one of it's strongest point
I usually get bored to have to spend 2 min in a 2h movie listening to people singing
Most of the time when i watch disney i skip the singing section cuz they are to me kinda of a filler thing
While honestly in this movie the "musical" section didn't feel burdensome and were flowing with the rest of the movie
Because the theme of the movie is kpop so it feel kinda natural to see them singing
And even if i didn't like some songs it wasn't just here to be "here" but the song was a central part of the movie and actually serve the purpose of making the story evolve
For example i think the song is takedown ? ( I watched in french so the songs were also translated which was disappoiting so i don't know the exact name in the us version)
I didn't like the song but because the creation of the song, the message, and the way it was included in the movie was a big part of the storyline
It didn't make me want to skip it when it started to play like i can do with disney song most of the time
