@Shoryu MagamiThemes And SongsAn Idol can pursue whatever theme of music they choose. From Classical to Death Metal. It's all up to the idol to pull it off and win fans over. Even if a person is not directly into the theme of music an Idol prefers to use, they can still be won over through an Idols fighting ability and natural performance.
Edit: Essentially yes, but I'm trying to be inclusive of all genres of music.
I hate forgetting good dreams too. I always try to write my interesting things down quickly. Whatever I can remember I try to write it down on the note in my phone.
