I think so as well. There are some masterpieces on 19 (Hometown Glory for instance), but 21 is just an amazing album. She deserves her incredible success.
21 is more produced than 19, in a good way though. 19 sounds a bit too raw (it's a debut album though). Anyway, Adele must be what happened best for women in music since 2000.
It depends Olof. Set Fire to The Rain is great to hear how powerful she sounds. Hometown Glory is great too. I'll Be Waiting is nice and cheerful, more than most of her songs.
