Country, and most 'Scream' 'metal'.
I actually have rare country songs that don't make me pull my hair out.
In rap, the C is silent. That said, Sturgeon's Law applies as well here as anywhere else.
I like a lot of pop stuff, tons of techno, metal, just about everything out there, but Country is an immediate NO.
And so help me, if I ever get a thermonuclear device and Rascal Flats goes to Houston...
It would be like hitting the lottery on Christmas.
