So, I'd say a backup feature that can save the playlists to a PC becomes really important. After a HD failure, I wouldn't really mind having to re-download all the tunes, because this would be a mostly automatic process - start it and leave it running over night. But I'd be extremely annoyed to have to rebuild all my playlists - this would be very, very time-consuming. There should also be no legal (copyright etc) problems with a backup function just for the playlists and not the tunes themselves, I'd really like to urge you to add such a feature. Will keep your customer's anger about a failed hard drive to a much more bearable level. Just stick it into the emplode program as File -> Save As and File -> Load :-)) Thanks!
