music you get through LimeWire (or any p2p program) depends on the file format. mp3 is probably the most common. Use the Library Pane's Explore button in LimeWire to see which kind of file you downloaded.

see the tips here about getting your downloads into iTunes http://www.kapsi.de/files/itunes.html

i get the message, when i put the blank cd in it says 'you have inserted a disk that has no volumes that mac os can read'

I think you get that message (and initialization options) if you were in the Finder and inserted a blank disk, or one somebody already used.
