At Metacritic, which assigns a normalized rating out of 100 to reviews from critics, the album received an average score of 74, which indicates "generally favorable" reviews, based on 14 critics.PopMatters's Colin McGuire found that with Because of You Ne-Yo "relishes in his disgust for a sophomore slump by fighting back with an album that leaves his first solo effort so far in the dust". He felt that the album "might end up being the best R&B album of the year." Similarly, AllMusic editor Andy Kellman noted that "the key to the album's potency and freshness is its differences from In My Own Words [...] Making it to number one on your own, writing a major hit for one of the planet's most popular entertainers, and qualifying as the heir to R. Kelly can have that effect."
In his review for The A.V. Club, Nathan Rabin wrote that the album "is a real sleeper that reveals considerable strengths upon repeat listens [...] Best of all, with a running time of just over 59 minutes, Because of You is largely devoid of filler, and it never threatens to wear out its welcome." Simon Vozick-Levinson from Entertainment Weekly noted that "indeed, the album is an unmistakable attempt to channel Michael Jackson's early work such as Off the Wall [...] and the effort often pays off beautifully [...] Ne-Yo's lithe falsetto puts the many others who've been labeled Jackson-esque to shame."Slant Magazine also compared the album's sensual ballads to Janet Jackson.Kelefa Sanneh, writer for The New York Times, found that Ne-Yo "got a silky voice and a clear knack for chronicling obsessive love and lust; maybe one day he’ll create a half-crazed R&B masterpiece. But in the meantime, Because of You is a likable little album: 12 girl-crazy songs from a boy who can stop anytime he wants. Honest."
