New input case for you: it's an interesting idea to have a operatic female vox in a metal band; however, her voice is mediocre (you'd know it's true if you know some names from the opera genre), and the music is not original at all. Does anyone know any similar bands (with operatic female vox) that are better than this? Let me know. Thanks!
Output:
Negative
