Digipak analysis

I have done a digipak analysis on 4 different albums, two of which are rap, one pop and one rock, I done these range of genres to see how different genres of music create and present their music, from this I found that a digipak design is down to creative interpretation, most digipaks follow a basic structure of a front cover, back cover, left panel, right panel and an extra panel, however how it's laid out and accompaniments that come with it is down to the artist/production company
