In his blog, Mark Cuban argues that album sales are a thing of the past, and that artists would be better served by using a "season" design in releasing music. One song every week or two for several months should yield greater sales than the combined album sale. Using an RSS feed to deliver samples of new songs would boost exposure. I imagine that a service like iTunes could reap serious rewards if it offered a nice aggregating system, allowing you to have several artists that you choose in one feed, and could offer a "season pass" design with discounts to those who order the whole "album" up front. Is there any reason this couldn't work? Cuban address the biggest issue I could foresee, that artists believe that the art of music is album driven, by pointing out that the business has changed. Artists who aren't willing to would be no different than the record executives that are fighting the shift in the industry. Much like a season set, this could be followed by a full length album for those that want packaging and such.
