As far as I can tell LimeWire does not offer playlists for your music. However having said that you say you are using iTunes for your defualt player. Every time iTunes playes a song it knows where the song is and lists it in it's library. You can do all the reorganizing you want with iTunes and burn them as well if you have a burner (either built in with a super drive or external). If your iMac has a built in superdrive then you are laughing. Toast is also an alternative and is the route I use. In using iTunes just drag all the songs you want on a CD into a folder and name it anything you want. Open the folder and then choose burn CD from the upper right part of the window. Its a little more involved if you use Toast and an external burner but not much. Hope this helps. Just post more questions to this forum if you have any.
