Brave debuted at number twelve on the US Billboard 200 with 52,600 copies sold in its first week, her first studio effort to miss the chart's top ten. It has sold 168,000 copies in the United States to date, making it Lopez's lowest-selling and lowest-charting album of her career.Brave has sold 650,000 copies worldwide as of 2013. It was generally viewed as a sales disaster and a commercial flop. The album also performed poorly internationally; only reaching as high as six on the Japanese Albums Chart and Swiss Albums Chart.
Reviews for Brave were generally mixed. Billboard said that "The album is another market-smart collection of radio fodder, rather than Lopez's artistic breakout. That said, no one does classy pop quite like she does."Dotmusic said that "Brave is actually one of her strongest albums to date."Allmusic said that "It's nothing more than modest music for mellow good times, but it's lively enough to be fleeting fun, with enough good tunes for a mild party, preferably one that's held at home."NOW said that "The songs are formulaic but catchy, and the production is meticulous."The Guardian said that "The sound harks back to the genre's golden age at the turn of the century: chunky bass lines, disco strings and purring beats dominate, and the brassy melodies are engineered for maximum dancefloor impact."Rolling Stone said that "J. Lo has turned away from the slick, minimalist future funk currently ruling the pop zeitgeist for chintzy production that screams 1990."
Other reviews for the album were negative. Entertainment Weekly stated that "Expensive beats and uplifting material are offset by listless vocals."Vibe was in a similar agreement with Entertainment Weekly, "That Brave on the whole is almost unapologetically poor isn't surprising—Jenny's never made a viable Album of the Year. But never before has the fly-girl-cum-cover girl been so listless."Yahoo! Music's review said: "Given Jennifer Lopez's thin voice, it's hard to expect greatness when she puts out an album. But Brave disappoints even for J.Lo-adjusted standards. Chock full of tepid dance grooves, Lopez's voice has never sounded so weak and marginal as on this record."PopMatters said that "Brave has neither a strong artistic personality nor boffo production, and as a result, ends up being just another disposable pop record with no redeeming value."About.com said that "The tracks on Brave that try to be club records fall short, containing such light beats and unexciting vocals, that few will be drawn to the dance floor."Entertainment Weekly placed the album at number 5 on their list of worst albums of 2007.
