What's so insulting about the label "storage jam". it doesn't seem like people who use it in a comparative way are being insulting or anything. just sounds like it did when people referred to everything back in the day as "cow funk" or any other term that immediately defines and qualifies something. (free form improv), that by it's nature, defies definition or any sort of clerical qualification. if people wanna use terms like "storage jam" to more easily call up comparisons in their mind so as to categorize and separate jams into their "proper place", then more power to em'.
