"Poetry it's not. Still, there is something delightfully escapist about Blackout, a perfectly serviceable dance album abundant in the kind of bouncy electro elements that buttressed her hottest hits (''I'm a Slave 4 U,'' ''Toxic''). Say what you will about Spears' personal life, but there's no denying that the girl knows how to have a good time."
"Spears needs to keep it grimy, because the alternative is a numbing blandness that makes you think too long about head-scratcher lines such as Heaven on Earth's "I fall off the edge of my mind.""

""Blackout," her first studio album in four years, is not only a very good album, it's her best work ever — a triumph, with not a bad song to be found on the 12 tracks."

"Blackout is terrible. Heck, even the title seems like a joke, considering the substance abuse allegations, even if her team tries to explain it away as a reference to "blocking out negativity and embracing life fully."
“She may no longer dance with flair, lip-sync on cue, keep her dress down, or even be judged a suitable mom, but Britney Spears can still turn up on some slammin’ new songs. The much-whispered-about, oft-giggled-over Blackout album, the singer’s first in four years, contains flashes of the zippy pop and propulsive dance beats Brit fans treasure, despite the singer’s, shall we say, distracting activities of the last year.”

“The Giorgio Moroder-inspired ‘Heaven on Earth’ is far more layered — which is a good thing, considering her vocals are especially airy here. Three different vocal lines take place over the throbbing beat, in a way similar to Moroder’s signature song, Donna Summer’s disco classic “I Feel Love.” Reciting what she wants as a come-on in one line (”Your love, your teeth, your tongue”), she tells her lover sleepily to “lay your head on my chest and drift away,” while simultaneously singing in a more bouncy style in a third lyric: “You’ve taken me so far away, one look and you stop time.” It’s one of the more complex tracks she’s attempted, with whispers sneaking in and out of other lyrics so that two or three songs could be happening at once. ”
“Like many of today’s young dance-pop starlets, Britney sounds like she’s looking back to the ’80s . . . . The Rihanna-esque ‘Radar’ (also produced by Bloodshy & Avant), sets Spears’s chirpy delivery to a bouncy beat, while the driving ‘Heaven on Earth,’ an early fave, is a throbbing throwback to “I Feel Love”-era Donna Summer.”
