I'm not sure how much longer they will be available, but I highly recommend listening* to all the songs here. There are 13 tracks from a live Amy Winehouse performance earlier this year in Amsterdam that serve to eliminate any doubt I may have had as to her musical skillz.
Not a pretty lady is Miss Winehouse, but she's got that voice. Seriously, where the hell does that sound come from? You've got this wilty little English-Jewish heroin addict and out comes a voice that threatens to bitch slap Aretha Franklin. And Aretha never sang, "What kind of fuckery is this? You made me miss the Slick Rick gig."
From all the things one reads about Winehouse, you've got to think she's not particularly long for this world. Unless she finds Jesus or some such thing, she'll likely end up dead in a hotel room in the next few years. But while she's alive, she's putting out some quality music.
It speaks to my observation that there seem to be more genuinely good pop music acts in Britain than in the United States. Remove Justin Timberlake from the equation and what have you got? Some guy named Bucky and a load of substandard R&B/hip-hop acts who have abandoned the English language ("Buy U a Drank"?! What kind of fuckery is that?).
*And just listen to them; don't download them, because downloading free music is bad.
