Packaging and
CD replication are done almost at the same time. By the time the CD copies roll out, the packaging materials are ready. But anyone who produces his own music and sells it straight to his or her crowd in the internet may no longer need to read this post.
Packaging is everything that has something to do with the branding of the music album. That includes selection of the album title, carrier single, theme, images and material.
Design, Titles and Credits. The packaging contains colors and images, the title of the album, the title of the carrier single (if any), the titles of the songs, the label logo, the credits, etc. The list of songs include the names of the music composers.
