The goal of Cocktail is to reivigorate interest in the album by adding a download package that includes liner notes, videos and other bonus content. But in typical Apple fashion, the new format is proprietery and tied in part to a new Apple tablet device that may not be ready until later in the year. To add to the confudion, the major labels have also banded together to create their own album bundle dubbed CMX.
With the album bundle horse race on, I'm betting that Apple will make a format announcement in September, perhaps tied to an iPhone and iPod touch app.
