A promotional package for a new album typically includes a copy of the album, artwork, and a plastic CD wallet without artwork. A common type of album packaging is a digipack, which is made from cardstock or heavy paper that can open like a book or have three parts to hold the CD in the center. Digipacks make the album look more attractive but can have drawbacks like peeling or separating over time. Typical music videos include elements like lyrics, chords, a storyline, main and other characters, and special effects to convey the melody, harmony, pitch, and rhythm of the song. Magazine advertisements for new albums vary in style depending on the music genre and target audience.
