The album has also drawn mainly positive reviews, with "Entertainment Weekly" magazine noting, "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." PopMatters.com called the album "a masterpiece of a record" and praised the title track's blend of "upbeat modern-day funk tempo, beautifully melodic backdrop and love-sick (in a good way) vocals...[it's] the perfect lead single off an album that is filled with number-one hits."

So far it has donned four singles, two of which seemingly failed to chart and one that failed to make top 20 impact "Because of You", "Do You" and "Can We Chill" and "Go On Girl". The album won Best Contemperary R&B Album at the 2008 Grammy Awards.
