Because, in this day of pre-fabricated soulless pop music, she's a throwback to an era where an artist got by on there talent instead of their image and good looks. When I was a child of the 80's, there were some ugly, old, fat people that made it big because of their music. I think Adele will be the return of that era. She'll let people believe that, even if they don't look like a model, if they're passionate, they can be successful,
In all honesty, i didn't watch the Grammy Awards, I don't watch many music videos, and I don't read a lot of music magazines, anymore. My first time seeing Adele was ages after I had fallen in love with the song "Rolling in the Deep". Even now, I'm not sure I remember what she looks like. I love her music, though. That's why I know she's a good artist.
