Musically, "Dangerously in Love" feels like a busier, tarted-up Destiny's Child album. The three-part harmonies are mostly absent; the song structures are more intricate, or at least more complicated; and the trio's unadorned R&B is sweetened with Middle Eastern rhythms, guitars, reggae and several well-chosen samples. [Matthew Knowles]'s affection for old-school soul is evident in the number of Shuggie Otis references and the Stax-reminiscent opening track, "Crazy in Love." With its horns, harmonies, samples and Jay-Z guest rap, "Crazy in Love" has more going on in its first two minutes than most albums do in their entirety. It's so impressive, the album never quite recovers from it; everything that follows seems enervated in comparison.
