I really like this Japanese rap that is being sung in the background, but it is being drowned out by voices and the music of the instruments during the scene. If I could understand Japanese it would be good, but unfortunately cannot.
Does anyone know the name of the rap being sung in the background behind the sounds of instruments at 10:20 here in Free! Eternal Summer, Episode 1?
If you turn up the volume loud enough you should be able to just hear it over the loud music.
