Sally Shapiro sings like an angel who married a bird. The Paul Leeny & David Loom-directed clip for “Love in July,” a light cut from the Swedish disco chanteuse’s new full-length “My Guilty Pleasure,” just so happens to include whale clouds-turned-whales and irrepressibly cute flying fish. It’s like watching an aquatic Homeward Bound on acid.  Wait, wouldn’t that be Finding Nemo?
