on the US Billboard 200, selling 48,000 copies in its first week. It charted three spots higher, but also with lower sales than her debut album. As of July 2015, the album had sold 190,000 copies in the United States. The album has sold over 600,000 copies worldwide by September 2010. Critical response Upon its release, Battlefield received generally mixed reviews from most music critics, based on an aggregate score of 63/100 from Metacritic. The Guardian writes "The 2007 hit 'No Air' gave you the breathy, cleancut gist; this second album employs the same tricks - almost literally, in the case of 'Let It Rain', which has a tremulous build-up and heroic chorus ("Let it rain, wash me clean," she commands). Squelchy electronics and a relatively earthy lyric ("Look in her eyes, she's mentally undressing him") give 'S.O.S.' an urban hue, and the clattering 'Let It Rain' is modern R&B worthy of Rihanna. Regrettably, though, Sparks sounds more comfortable with power ballads such as 'No Parade'; and there's an inner Pat Benatar struggling to get out on the title track. OK if you like this kind of thing." Slant Magazine writes "Sparks is a pop artist and makes no bones about it here. Much of the album's running time is filled with the kind of soggy adult contemporary pulp that weighed down both the singer's self-titled debut and Leona Lewis's Spirit, and the addition of two paper-themed bonus tracks, "Papercut" and "Postcard," on the deluxe version of Battlefield doesn't help matters. One wonders if it would have been a smarter move in terms of career longevity to try to build on the urban audience she started to cultivate with 'No Air'." Entertainment Weekly said "Battlefield certainly delivers on the artistic end: It's packed with more hooks than a fisherman's tackle box, none better than on the gorgeous title track, which sports a soaring chorus. Resistance is futile when Sparks, showing heretofore unseen vocal dexterity, takes to the dance floor to ward off a vixen who's barking up the wrong boyfriend. There is actually enough potential hits to keep the singer in heavy rotation until well into Idol's 10th season." Digital Spy also gave the album a generally mixed review, writing, "Nothing here is as irresistible as the single, a brilliant update of the '80s arena rock sound that deserves better than its middling chart performance, but several tracks aren't too
