I have that response to some of their songs, and they are certainly not my favorites. Largely, I find it is a mixing and tonality thing. Like many musicians who aren't terribly strong vocally (or lyrically), they tend to make up for it by making the music part louder.

However, all of my CDs have long-since been turned into MP3s and put on my file server. In my office (where I type LJ entries), my folk directory is playing 24x7, so it's somewhat random as to who is playing when I'm posting.

I rarely listen to one artist straight through, as I find it boring.
