Do Rascal Flats, kenny Cheney and Taylor Swift sing real country songs or just countrified pop tunes?

Rascal Flatts and Taylor Swift are 100% pop and they aren't the least bit country! As for Kenny Chesney, he actually has a coupleof songs that sound country but, overall, he mainly plays island music! Seriously--I think Chesney thinks he's from Jamaica or somewhere around there.
