Adele is a magician, and nothing less. The way her lyrics blend with the jazz-pop genre she has established is nothing but magnificent. I have been hooked to this album since I downloaded it sometime last year. My favourites being Set Fire To The Rain, Someone Like You, followed by Rolling In The Deep.
She has achieved the success she deserved. Although 19 established her as a singer, 21 just made the world aware of why she deserved to be counted in one of the best singers in the world.
