Honestly all I can really say is I guess we just have different opinions. I loved Future Nostalgia. I thought it was a great album, even if it's technically not doing anything new. However, I found everything she did before it to just be okay. I do think it's a bit ridiculous to say she can't sing. As @Hooked-On-Knee said, she's not necessarily the strongest vocalist, but I really like what she does with her voice. Not everyone needs to have a voice like Ariana or Mariah or even Selena Q to be considered musically talented.
That move is exclusive to Demi
