There is a slightly crackly feel to the sound which adds to its classic feel. Some of the music is really moving and quite sad, as there are gorgeous piano lines, frazzled beats and evocative lyrics on many sections. There's a wide range of subject matter, from broken families to modern sexual culture to a quirky section describing his favourite types of food. It really is the greatest album of the 21st century so far - tremedously innovative, it just has everything. If you don't have it, you need it.
