As a folk musician in my 20s, I don't find either of those musicians appealing. The songs I've heard from them sound more like pop than folk. I only play traditional, but traditional music will always be appealling to certain people. It is my belief that more pop oriented music easily becomes outdated and dies out. People will still be singing Child ballads in 100 years but probably not either of the musicians mentioned. I liken it to architecture, if you see a thatched-roofed cottage or log cabin built a few hundred years ago, then look at a suburban style housing development from the 70s, modern commercialism can not compete with a traditional artform.
