Music Review: Blackpink K-pop star Rosé’s debut solo album ‘Rosie’ is heartfelt, but slightly sleepy

Across “Rosie,” titled after Rosé’s nickname to communicate a kind of personal intimacy, the singer goes to great lengths to detach herself sonically from her band. Unlike Blackpink’s high energy electro-pop output, Rosé’s solo material is that of a coffee-house dweller with a sideline in romantic drama. But don’t expect finger-plucked acoustic guitar balladry exclusively — “Rosie” is reserved in some moments, full of life in others.
