10 minutes ago I had no idea, who this "Adele" is. I know it is my fault, I checked wikipedia, She is pretty famous by now, but I don't listen to radios and stuffs like that. Anyway, I listened to the songs You mentioned. Though this is not the style of music I listen to, I have to admit, She is really good, I hope She will have a nice career.
It's hard to choose one, but right now my favorite is "Don't You Remember" from her album "21." It's a great one to sing -- soulful, full of feeling. I think her cover of Dylan's "Make You Feel My Love" is perfect -- I can't imagine anyone doing a better version.
