Classified is the second Sweetbox album and the first album to feature Jade Villalon as the frontwoman and songwriter. Released in 2001, the album was made in three different editions. Sounds on the album include pop, dance and rock, with all of the songs based on various classical pieces, many borrowed from famous film themes. With Jade Villalon's songwriting style, this album saw Sweetbox's sound change from the R&B influences of its past. Three additional songs were written for the album; "In the Corner" and "Heartbreaker", which were released on two Sweetbox demo compilations, and "Happy Tears", which was released on Jade's final album under Sweetbox, Addicted.
