I've had this argument a gazillion times, and I'll probably have it a gazillion more. It isn't snobbery to correct someone's improper use of a word, it's pedantry.

I completely agree with the dictionary and the pedants (N.O.I., I R 1) about the use of the word. I also like a lot of contemporary accoustic music. The oldest song you can think of was new at some time.
