#6 is my favorite on modern times, too.
#2 is amazing, but its the only song i know from that album.
and i like love and fear and workbench songs, but i could not name a best song..
dont know the rest ;)
Girl in the War is the only other song on that album that's really great. I wouldn't necessarily recommend the album, but those two are excellent. Of the other songs on that list, I think you'd be most likely to enjoy Tom Russell.
