I have heard the new chart-topping granny Madge single '4 Minutes'. Urm, it doesn't work for me. I can't speak for the rest of 'Hard Candy' though. The bits and pieces that I have heard is, well, rather bland.
I like the new Portishead 'Third'. 'Machine Gun', at least in my impression, is slightly reminiscent of
Scott Walker's 'Tilt' due to the explosive use of percussion. Interesting!
