well... I can't really help with your situation, but I like folk. Specifically folk-rock like Simon & Garfunkel. I have an electric guitar, though - so I won't be doing too much folk off the bat (I'm a new guitarist :)).

My favorite is Baby Driver by Simon & Garfunkel - their least folk song, probably... their other stuff is good too, like El Condor Pasa and the Sparrow.
