I still think i'm right about the way the realtracks are recorded. as a guitarist playing in the key of C if i played C-D-G i'd play the D as D7. In G it would be G - A7 - D. faced with that chord progression i bet the players on the realtracks do what i would do. the OP's original chord progression is now so far gone i can't be bothered to look it up but i'm sure guitarists will know what i'm talking about. if only the OP had tried a midi style maybe we would have the answer by now.
With all respect... You're talking about the II chord being a 7th... I believe the OP was complaining about the V chord being forced to a 7th.
edit: of course I could be wrong in assuming the OP's chord progression is in the key of G... He did say "the genre was country."
