Though her track record as an album artist isn't as unblemished as some, including the Recording Academy, would have us believe (though not bad, The Globe Sessions was a disappointment following its self-titled predecessor, and C'mon C'mon was MOR pap at its most painful), Sheryl Crow remains a consistently impressive singles artist. From her charmingly belligerent debut, "Leaving Las Vegas," to 2005's lush, quietly contemplative "Good Is Good," Crow hasn't released a lead single I haven't loved. That streak, it seems, would be broken by the singer-songwriter's hippy anthem "Love Is Free," which chugs along like a well-oiled parade float but is a little too cute-n'-bouncy for its source material (the failed federal response to Hurricane Katrina), if not for a technicality: The single was preceded by the airplay-only "Shine Over Babylon," a more sobering take on current events that is sonically closer to "If It Makes You Happy" than "Soak Up the Sun."
