A Digipak is a type of CD packaging made of card or paper with a plastic tray that holds the CD. Digipaks are commonly used for special releases to make the product more desirable and increase sales. The cover artwork is important for relating the album's genre, artist and providing a visual connection to the music. The front displays abstract images related to the music while the back provides track information. Digipaks help sell albums by intriguing people with their design and linking to an artist's theme and promotions. However, demand for Digipaks is falling due to the rise of digital music which does not utilize their visual design aspects.
