I'm a professional DJ that is doing a massive overhaul on tagging my music collection. I have a large about of live albums and they are really getting in the way of deleting duplicate files since the same song will come up when I select display duplicates in iTunes (Apparently this only works for same artist and song rather than knowing if it's a live album or not). I use Dupin for deleting mass duplicates, but this isn't even cutting the task as I want to keep the live version as well but just have it tagged properly in the song field. Basically what I want to do is be able to select lets say 12 songs from a particular album and add (Live) to the end of the title field without having to manually type that in for each song. Does anyone know of a way to do this like I suggest or maybe automatic? Thanks in advance!
