Pre-Production Research: CD Cover Codes and Conventions

Before I can begin to design my pre-production, I must first define the typical conventions that a CD Cover may contain. As the word 'convention' means "a way in which something is usually done", then I need to identify the features all CD covers have in common.
The most obvious conventions would be the artistis name, the album title, and the main image. All three would have some link to each other; an example would be Regina Spektor's album, Mary Ann meets the Gravediggers (featured left). The main image, a woman walking away from three gravediggers, expressibly links to the album title. While the main image is mostly black and white, the flowers the woman (a.k.a Mary Ann) is holding are red; this colour scheme is reflected in the artists name, which stands out against the simplistic black and white background. The flowers themselves are wilting, indicating that they are dying; this links back to the idea of gravediggers, which the album is called.
Another notable aspect about the CD cover, is the fonts used. Part of the album title is, not only capitalised, but also in a slightly larger font; this attracts the attention of the audience and focuses us upon what the album concerns. However, it also informs us that this album is likely to be more of a abstract collection of songs: 'and other short stories'. This makes the CD stand out from more stereotypical albums; rather than replicating other artists and singing about money or relationships, this artist seems to revert to using music to tell stories rather than using it to brag. In contrast to the album title, the artists name is presented in red, linking to the wilting flowers, and stands out amongst the simple colour scheme. The font it is written in is also different to the album title; again, this is to make it stand out and also clearly define who the singer is. 
These are three items that are widely accepted as the main conventions of the front of a CD cover; the back, however, contains a number of different conventions: 
 *  A list of song titles
 * A barcode
 * Copyright and year
 * Name of the company record
 * Who the album has been distributed by
While this album contains all of the conventions listed, it also includes some others that are relevant and could aid me in discerning what should feature on my design.
Although it is predominately a CD, you learn that the album also features a DVD, one which references a previous album sold by this artist. However, it does contain the music video to one of the songs featured on the disc. Considering that I will be creating a music video for my production, this is a clever idea that could feature upon my pre-production.
Another item that is not a stereotypical convention of CD Covers is the picture format, colour mode, the region code, disc format, duration, and the language and audio content. These are all relevant as they inform the consumer which countries this disc can be played in, and also the length of the album itself. Again, these would also be useful to include for my pre-production.
My final point concerning the back of this album is the use of an image. It is arguable that this is an uncommon convention, but it is one that is used by artists; the image itself is one that conforms, not only to the colour scheme, but also the albums theme. As such, I need to consider if this is an item that features upon the backs of my selected artists CD covers, and if it should be included based upon my research.
