I must say it's Adele and Shania Twain. Adele's voice is simply majestic. She really makes me feel that she's just there singing the song for me. It reflects on her songs how every heartache and heartbreak. She makes sure that every sound that comes from her mouth will be very endearing. She is very cute too. I love on how she curse and laugh when she was in the Carpool Karaoke show. Shania Twain! Oh my! I love on how she sings. She's like a storyteller and make sure that she's not just singing that she is imparting messages through her songs.
