That is really nice piano "flavoring". Hard to define that as a style/track though, I would think... it is almost "fills" - which would be GREAT to have. That would be a great addition on almost every area. The nylon guitar track (Brent) is INCREDIBLY useful...

I don't think of organ in the same context as piano (or keyboard) - so if you want to talk about that, we need some organ tracks with real "bite"... our organs are a bit "wimpy" - timid, lost in the background...

The last (best) example of "piano carries the song" in Country was "I Drive Your Truck"...

So that might be one to "capture"...
