I personally am a big fan of female artists with strong voices, clever lyrics and strong piano background... mostly because that's what I like to play haha...
But I recently rediscovered this song when I transferred my old iTunes to my new computer and I love singing along to it. A little melancholy, but still enjoyable... at least to me haha :)
