I use itunes 2.0 and whenever i dowload a mp3 from Limewire I use an application called iTunes Associator 1.6 . It is great since it will convert all my mp3 files to itunes, so whenever I double click them they will automatically open in itunes. This file can be found at download.com and searching for the term iTunes Associator. Its nice and simple to use. I hope this helped. If you have any more questions E-Mail me at KDGE@mac.com
