You can create playlists in the Library ... see the bottom of
http://www.limewire.com/english/cont..._library.shtml
but many users prefer to use an application like iTunes or WinAmp to organize songs in a more useful way. If you are going to use the limewire player, be very careful not to use the delete function to remove any songs as you will delete them off your computer instantly.
I hope this helps
