We recently reported idol group MBLAQ's "Baby U!" secured the #2 spot on the Oricon chart three short days after being released. To add to their list of achievements, "Baby U!" seized the #1 slot�on�Billboard under�the Japan Hot Animation category. Even before the song was released, "Baby U!" was selected to be the theme song of the Japanese animation 'BEELZEBUB' and secured the #1 spot on the Rekochoku chart for three days straight. This is the second Japanese single the boys have released after "Your Love" that was released this past May, and MBLAQ is without a doubt making a mark in the Japanese music industry.
