Looking for a Novel with a Female Protagonist Who Mainly Sings or Writes Songs

Are there songs that focus on songwriting and singing? Are there single female protagonists? It doesn't matter how much the heroine's role is. Anyway, there can't be other romantic partners. In terms of career, songwriting or singing is the main focus. You can participate in variety shows, write scripts, etc. It doesn't matter what other acting directors are.
