1) Electronic dance music (EDM) CD covers commonly use bright, bold colors like purple, blue, and green with an enhanced light glow to evoke a nightclub setting. Artist photos are sometimes featured but DJ covers often omit faces to maintain mystery.
2) Designs also include abstract shapes, landscapes, and artistic alterations of photos to make them stylized. Fonts are typically artistic deco styles. Song titles are larger than artist names.
3) EDM CD covers can be categorized into groups based on design elements but designs ultimately depend on the artist and music, with established artists focusing more on music over themselves.
