Yup, that's why I like iTunes, you have the option of only buying that one song ... of course, it's much easier if a friend on the network has already bought the song, then all I have to do is connect to the server ... :spin:
Since you recently stocked up on Hawaiian music, I have no suggestions to add to that collection :D For jazz, have you heard of Jane Monheit?
New music I'm listening to is Michael Buble, Nickelback, Evanescence ...
