EN Music Takes-
Mori- Puts the most time and money into her music and has gotten the furthest with it. While not very talented, she fills a niche and took advantage of the momentum she got from debut.
Kiara- More talented than many would give her credit for, but chicken voice turns a lot of people away. Easily the best performer in EN (as in song, dance, and stage presence) and has a lot of passion for being an idol.
Ina- Pretty talented too, though she doesn't have a lot of range. If she releases more music, I don't expect it to diverge too far from how Violet sounded.
Gura- One of the top singers in EN (either her or Irys is the best), but seemingly doesn't want to do that as badly as we'd all like. She would benefit greatly from releasing a full album or EP. Lots of potential here, she just needs to do more with it.
Irys- The opposite of Gura: while extremely talented, nearly all of her music is generic and boring. Rapid-firing garbage has caused many people to lose interest in the vsinger's music, which is a fucking shame.
Kronii- She fucked herself over with the way she released her song. But she sounds decent. I'd like to see more from her, especially since her voice is so unique compared to many other Hololive members.
Mumei- I'm surprised with how well her song has been doing so far, but the theme of the song does a good job at setting it apart from other Holo songs. She's talented at singing, but not quite professional level. Unpolished, with great potential.
Bae- Has my favorite song from EN and has incredible range. The cover she put out before her original almost feels like it was sung by an entirely different artist. Could potentially be Gura/Irys level.
