Asilo of Inquirer.net wrote, "...the 10-track collection is a career-boosting showcase for the Popstar Princess’ ever-expanding skills as a vocalist, as well as her continually evolving interpretive ability as a performer...The 27-year-old singer-actress evinces growth and shines even when she isn’t compelled to show off those steely pipes with attention-seeking birit notes.
