There are thousancds of Styles available for the BK9 so your bound to find some that suit your Country songs. I just bought a Thumbdrive on Ebay loaded with a few thousand. And like the sounds they are all very editable to get what you want. I've spent countless hours first on the BK7M and then the BK9 editing Styles, Sequences, and Sounds to get mine where I like it.
There are lots of choices but I'm very happy with the BK9 and when I feel like jamming and kicking some pedals B3 Style, it does a great job for a 16 lb. keyboard vrs. the 400 lb. Hammond.
