From Spears's bizarre head-shaving incident to her parental custody struggles to her critically reviled MTV Video Music Awards performance, most of the year was an exceedingly long train wreck for the pop superstar, and those events, to some degree, inform BLACKOUT, which stands out as a defiantly bold dance-pop offering. <p>Buoyed by the massive club-oriented hit "Gimme More," the record sports a slick, nearly armor-like techno veneer that extends to every track, from the pulsing above-mentioned single to the tinny "Toy Soldier" to the R&B-tinged "Why Should I Be Sad." While Spears takes on media criticism most directly on the Vocoder-laced "Piece of Me," she also offers up some giddy escapism, most notably on the floating synth-pop of "Heaven on Earth," a strong contender for BLACKOUT's finest moment. Although the album doesn't erase many of Britney's woes, it arguably serves as her best record since OOPS!... I DID IT AGAIN, and that alone should make it a delight for many fans.
