It doesn't matter whether people thing the Mumsies are folk or not. They are hugely successful for taking the Coldplay formula and repeating it on acoustic instruments. Not my cup of tea, but good luck to 'em. Personally, if I'm not listening to the sort of folk music I enjoy, I'd far rather be listening to Gnod, Wooden Shjips, White Manna, The Sufis, Mmoss, The Belbury Poly or the mighty Goat. Just spare me coffee table music in any genre...
