Awe, we've always had a heavy dose of country, you just notice it more now because a persons three requests are less likely to be broken up and with fewer people requesting they come around more often.
A few months back I did try to remove some of the older "twangier" country music because it just felt too outta place. But the Kenny Rogers, Tim McGraw, Faith Hill, Shania Twain, Martina McBride stuff is very mainstream and very often winds up on pop stations these days.
Stay open SG, you might wind up liking some of it. I used to HATE country music with a passion, but eventually the likes of Shania and Martina won me over.
