After testing all music file sharing programs on my i-mac os9,limewire came out tops.It seemed to improve the more i used it.Recently i upgraded to iBook mac os 10.1.4.The same percent of downlownds appear but barely any even begin downloading.I don't know if this is related but after transfering my mp3 collection over to the new itunes,half of them seemed to reduce in lentgh then the whole collection dissapered forever. I would be grateful for any advice. cheers job
