More 5G Than Man
I had got the impression they were a kind of folky indie sort of thing and that indie wankers will just assume anybody who doesn't like NMH doesn't "get" Magnum's voice. From the little I've heard, his voice is unusual and his technique poor.
You're pretty much right on in your assumptions. They're not a terrible band, but really not to my taste. It's just one of those one-off songs that I like, but not the band in particular.
