answer:Why couldn’t you use iTunes and its rating system and simply use “Smart Playlist” feature to sort and delete? You seem to be increasing your work load. (I didn’t find anywhere near as many worth keeping as you did – but then I am much older and have different tastes. My daughters found some though.) Load them into iTunes, skim them using the iTunes sampling feature – rate them, then delete all those you didn’t feel worth rating by opening a Smart Playlist based on the date they were added and sorting by rating – deleting the unrated.
