Word abuse: barnstormer

Does anybody know what a barnstormer is? My friend Mr. Webster defines the noun as such: "1 : one who tours through rural districts staging usually theatrical performances 2 : one who travels from place to place making brief stops (as in a political campaign or a promotional tour) 3 : one who pilots an airplane in sight-seeing flights with passengers or in exhibition stunts in an unscheduled course especially in rural districts" OK - it basically refers to a manner of travel. So why is it always used to imply a totally loud, completely bitchin,' dripping-with-attitude party of a song that riles up a crowd to "hoots and hollers" (future "Word abuse" candidate)? Check the abuse: "The rock legends played a 16-song set that included staples like 'Stairway to Heaven' and 'Kashmir,' and they closed the show with the iconic barnstormer 'Rock and Roll.'" "Their debut record Hello Master is a barnstormer of unabashed rock fury." "Thanks to pre-digital age tubes, this Zeppelin-esque barnstormer hums and crackles with warm fuzz." Who started this nonsense? I can actually understand this term's inclusion in the country genre. I mean, who can truly dissociate a Toby Keith song from a steaming heap of cow shit covering, or storming, if you will, a barn? But it has no place in rock 'n' roll. Zeppelin and farm life just don't mix. It's funny -the only way I read "barnstormer" now is in the voice of Mr. Hanky: "Howdy ho - that song shuuuure is a real barnstormer."
