Larry Flick of Billboard wrote, "Wildly infectious hi-NRG/house music confection is delivered with lots of charisma and diva charm by lead singer Meja. Producer/writers Bag & Snowman have concocted a sing-along chorus that embeds the brain upon impact, and melts it into a white-hot arrangement of rolling piano lines, and butt-shaking beat breaks. Although story will begin at club level, this record has summer pop radio smash written all over it. It gleefully brings
you back to the days of platform pumps and disco togs. Have a nice trip."[5]
