I love her voice and how she sings. At the same time I have to say most singers usually specialize in a style and won't do well in others. Moona and Enna do really well in vocal songs like slow k-pop, enka and jazz but not so well in faster paced lyrical focused songs. Just like Calli is good at rapping but struggles with other genres. And I don't think anyone could beat Ollie at grunge / punk.
