On February 12, 2007, Ivy’s second album, Vol. 2 – A Sweet Moment, was released, with the lead single “Sonata of Temptation”, which sampled Beethoven’s Fur Elise, performing very well on the charts. (its PV is cosplaying Final Fantasy VII movie).

Despite its success, the song’s music video caused controversy, as it recreated a fight scene between Tifa Lockhart and Loz from Final Fantasy VII Advent Children, without proper permission.
