Well let's examine this
Country (I believe) originated from the south.
This technically makes it Southern Folk.
Southern Rock (obviously) originates from the same place as Southern Folk (a.k.a Country) but is a step above, making it heavier, therefore, rockier.
As everyone knows, you can't beat a good bit o' rock.
Therefore, yes, Southern Rock is country made awesomer.
FYI, what's the next step above Southern Rock?
Logically it'd be Southern Metal
a.k.a PANTERA \m/
