This won't be for everyone, but for those who have a PS3 and an Ipod it may be useful...
If you plug the Ipod in via usb the PS3 recognises it but says that there is no music, however if you press Triangle, and select display all some folders appear, go into the Folder called Ipod_Control and move to the Music folder, in there all folders are indexed F00 F01 F02 etc, each contains some songs.
The clever part is that if you press triangle on the Actual music folder and select copy, it will copy all songs to the PS3 and will automatically put them into Folders for each album.
If anything its a good way to back up your music files!
Hope this is useful to some people!
