Can I do this?
 

Ok, this may be stupid, but can I play already made CD's on Limewire... like say I went out to the store, bought................. Barney? WICH I DIDN'T.... can I play that CD on Limewire, or no?

If you mean you want to play the songs from within limewire, you would have to copy the songs to your hard drive then add the songs your LW library. Then you would be able to play them from in LW.

To add songs to LW go to Tools>Options>Shared>Add then select where the songs are located on your hdd.
