What is the function of a digipak?

A digipak is a package of your CD along with special features included to interest your fans and increase value to your music, the pictures used in the digipak are generally taken for the sole purpose of creating the CD package, this makes these images exclusive to those who are willing to buy it. The reason why people have Digipaks instead of just selling their songs on iTunes is for exposure, having your music on the shelves of the music store exposes you to a huge number of people willing to give you a try. Another reason is to treat the fans, by buying the digipak they can have a physical copy of their favourite artists music so they can keep it for years to come, it may even serve as a memory for the good times they once had listening to an artist. Its a good way of making money and increases the popularity of the artist because of the amount of marketing that goes into selling a digipak.
