Textbooks or audio CDs? (roeutena)

See… People are more creative than decades before. Now they don't entertain only by music and dance, but also cute by CD books! Oh… my first impression seeing these Korean audio CDs was: omg... They're just so… they look like my English/Japanese (language) or maybe computer science textbooks that usually come with CD on the last page/back cover.

Humm… also technology today... You can buy your songs online. Who needs CDs? "All we need is the collection of the pictures", right?
