If you have you iTunes library music in say AAC but in this case want to have Apple lossless files for an archive or maybe a friend then you are faced with changing iTunes preferences, ripping the file(s). Determining which are which in your iTunes library ,both AAC and Apple lossless files are .m4a, and don't forget to change iTunes preferences back. Similar multi step clunky wastes of time processes are necessary for all other file types. Apple intended iTunes for adding music to the iTunes library and was very successful in making it unattractive to use it for utility ripping. A good solid stand alone ripper is necessary for anyone who serious about music as an avocation. I personally use XLD.
