Let me have J-pop fan advice for original Jpop channel

I'm Kotira, Jpop amature songwriter. I'm creating some Japanese music video with a help from AI. (but all melody is made by me)
In these contents, i try to use Japanese music way as much as possible.

– Song structure (Verse – Pre Chorus – Chorus)
– Syncopation
– Modulation
– Code structure (e.g. Am-F-G-C)

I want to have more listener for my channel.
For that, could you advise me what type of music i should try.

For video quality, i know i need to improve…
