If you have an ipod just pull them off of that... You have to make the files un-hidden. They will be in the music folder. They are coded as a whole bunch of random letters and numbers but thats just the itunes code. If you copy them from the ipod to the computer then use itunes to import the files and folders, itunes will do all the work for you setting up the library and renaming the songs and find artwork and such... There are more in-depth directions on how to do this if you search it on the internet... JFGI (Just Fucking Google It) lol
.... or you can ask me and i will try to guide you through it
