[pales, ashamed of his musical ignorance]

(The only ones of whom I have listened to a sizeable fraction of their works are the Beatles, the only other one of whom I've heard a non-trivial amount is Bach, and the only other ones I've heard about are Armstrong and Eno.)

Folk music on the other hand doesn't seem to evolve with time that much -- I've over- or underestimated the age of certain songs by as much as a century. I mean, would you have guessed that "Finnegan's Wake" is [rot13: sebz gur rvtugrra-svsgvrf] whereas "The Fields of Athenry" is [rot13: sebz gur avargrra-friragvrf], just from listening to them?
