Of course, first you have to wade through the obligatory one-note singles (Rodney Jerkins's "Lose My Breath," an explosion of marching-band snares and heavy breathing, and the even more limited thug paean, "Soldier"). But after the limp erotica of "T-Shirt," sturdy melodies and themes dominate, allowing Knowles, Kelly Rowland, and Michelle Williams a framework for their underrated harmonizing -- remember, unlike so many acts that share their target demographic, these girls can actually sing. "Bad Habit," underpinned by heart-tugging strings, and the buoyantly funky "Free" are the best of half a dozen fine tunes mourning the end of love and celebrating new independence.
