This Week's Music (August 25, 2009)

Hello readers!  Here's a quick round-up of some of this week's notable new music releases. I'm just pinch-hitting for Radhika as she settles into her new schedule, so she'll be back to posting the good stuff soon. This week's new albums include the Arctic Monkeys' third album Humbug; special collectors editions of Radiohead's Amnesiac, Hail To the Thief and Kid A; Matisyahu's Light; Imogen Heap's Ellipse; and the soundtrack to the new Fame movie.
