I guess it depends on what you listen to, my kids like to listen to the pop stations on XM (Z100-KISS), her music has been in constant rotation for much of the last 6-8 months.
here's a good starting point - maybe her best performance ever:
And from there go to "Rolling in the Deep". The new "Set Fire to the Rain" track is pretty good as well.
God damn. I know and love Adele, but when I'm not actually listening to her I forget just how amazing that voice is. It just doesn't sound like something that somebody learned how to do.
