Love is often presented as something easy, a matter of simply following your heart. But in actuality, it's rarely that effortless. Several of this week's songs reflect the sour, absurd, and heartrending aspects of intimacy: Wet, one of Robin's picks, mourns the fact that "love is not enough." Singer-songwriter John Grant muses on its absurdity in his darkly comical "Love Is Magic." Also on the program: the classic guitar rock and pop of Montreal singer Michael Rault, the urgent music of D.C. post-punk band Flasher, and the glitchy, atmospheric electronics of Tim Hecker.
