I'll vote for more country shuffle styles as well as country swing.
(sometimes you can interchange them but there IS a subtle difference)
Just a small quibble Don, I wouldn't call your "shuffle5" example a shuffle.
It's more like (what we call) "straight 8".

I get your drift though, thanks for including those clips.
Also thanks to Jon for including specific song examples.
That's got to be a big help in trying to interpret what people are actually asking for.
